Sunday Wild Card Playoff Preview 2015

Sunday Wild Card Playoff Preview 2015

by Vince Verhei (CIN-IND) and Aaron Schatz (DET-DAL)

The narrative that links the two Sunday wild-card games is four teams seeking long-awaited playoff success. Cincinnati has lost on three straight wild-card weekends. Dallas is just 1-3 in the playoffs with Tony Romo at quarterback. Detroit, of course, barely even gets to the postseason in the first place. Only Indianapolis has had any recent playoff success, and that took a ridiculous comeback against Kansas City last year... which was followed up a week later by a colossal egg-laying in Foxborough against the Patriots.

The last time the Bengals traveled to the Colts was Week 7, and things went badly for the men in orange and black. Playing without A.J. Green, Andy Dalton dropped back to pass 41 times and gained just 109 net yards, an average of just 2.7 yards per play. He got little help from a running game that produced only 12 carries for 32 yards, and the Bengals' first eight drives were all three-and-outs. Though the Cincinnati defense somewhat contained Andrew Luck, they were trampled by the Colts' ground game. Indianapolis ran for 171 yards, with Trent Richardson, Ahmad Bradshaw, and Dan Herron all topping 5.0 yards per carry. By the end of the day, the Colts had outgained the Bengals 506-135, beat them in first downs 27-8, and walked away with a 27-0 win.

It was a completely dominant victory, there's no doubt of that, but was it a sign that the Colts are a terrible matchup for the Bengals, or just a fluke? In some ways, that game must leave Cincinnati worried about this weekend's contest (Green's health is once again a critical concern, and the Bengals' run defense was a big problem all year), but by and large the two clubs could hardly be more closely matched headed into the playoffs. Indianapolis finished 12th in overall DVOA at 4.7%, while Cincinnati was 13th at 4.6%. This also looks like an even match in Weighted DVOA, where the Colts also have a slight edge (1.8% to 0.5%). It looks like the Colts' big win in October was simply an incident of one team catching the other on one of its bad days.

The Bengals were up and down all year, finishing next-to-last in variance. They were erratic on both sides of the ball -- 23rd in variance on offense, 31st on defense. When Cincinnati was good, it was very good, with seven games over 30% in DVOA. But the Bengals also had seven games with negative DVOA. (For comparison's sake, the top five teams in DVOA -- Seattle, Denver, Green Bay, New England, and Baltimore -- averaged 8.2 games over 30% in DVOA, but just 4.0 games each below 0%.) Though we are going to look at each team's strengths and weaknesses and what the key matchups figure to be, to a large degree the game will be decided by which version of the Bengals decides to show up.

WHEN THE BENGALS HAVE THE BALL

UPDATE: On Saturday afternoon, A.J. Green was formally ruled out for this game after his Week 17 concussion against Pittsburgh.

It's no secret that the Cincinnati passing game has been subpar this season, but the problem has not been in protection -- the Bengals gave up just 23 sacks this season, and only four teams were better in Adjusted Sack Rate. The Colts, as a team, have a decent pass rush (tied for ninth with 41 sacks, and also ninth in Adjusted Sack Rate), but that's a result of team pressure, not any specific dominant rusher. Jonathan Newsome, a fifth-round rookie linebacker out of Ball State, leads the team with just 6.5 sacks, a total that tied him for 40th in the league. So we shouldn't count on Indianapolis rushers winning one-on-one matchups with Cincinnati linemen.

The problems for the Bengals, though, haven't often come on sacks. No, they have come when Dalton has actually had time to throw the ball. The Bengals ranked 26th in DVOA on non-sack passing plays, and the six teams below them (the Jets, Vikings, Titans, Buccaneers, Raiders, and Jaguars) were a sorry lot indeed. A large part of that, of course, was due to Dalton's 17 interceptions, tied for third-most in the league.

The long ball was a particular problem for Cincinnati -- no offense in the league had a worse DVOA on deep passes (those thrown to targets at least 16 yards beyond the line of scrimmage). In fact, the Bengals were one of two teams this year (the 49ers were the other) with a higher DVOA on short passes than on deep balls. The good news for Cincinnati is that when you're playing Indianapolis, you want to throw short passes anyway. The Colts defense was sixth in DVOA against deep balls, but 30th against short passes. In particular, they were vulnerable on short passes to the offense's right, where they were 30th in DVOA. Not surprisingly, that's Greg Toler's side of the field. The charting data we have so far confirms what most have been saying about the Indianapolis cornerbacks: Vontae Davis (4.7 yards allowed per target) has been much better than Toler (7.8) or nickelback Darius Butler (8.7). Davis, though, rarely strays from the offense's left side of the field; so far we've only charted him on one target to the right side, and only six over the middle. We have only counted five missed tackles for Toler so far this year, so it's not a matter Toler struggling to make plays. Instead, it looks more like he has been giving up big cushions and allowing short stuff all day in an attempt to take away deep passes.

Cincinnati's most common receiver on short right passes this season has been A.J. Green, followed by Mohamed Sanu, Jermaine Gresham, and Giovani Bernard. This makes the health of Green critical. Green suffered a concussion in the Week 17 loss to Pittsburgh. He has been limited in practice this week, and under the league's concussion protocol, he must see a neuropsychologist Friday and a neurologist Saturday before being cleared to play.

The other weaknesses in the Indianapolis defense are related not to direction, but position. The Colts are in the top half of the league in DVOA against No. 1 wide receivers, No. 2 wide receivers, and all other wideouts, but are 27th against tight ends and 31st against running backs. There were 12 players this season who gained at least 80 yards receiving against Indianapolis; half of them were tight ends, and one other was a running back. That's not great news for Cincinnati, though, because Bernard, Jeremy Hill, and Rex Burkhead were just average as receivers this year, and Jermaine Gresham was, as usual, one of the worst receiving tight ends in the league.

If there is a shot for Cincinnati to get some big plays in the air, it could come against blitzes. According to ESPN Stats & Information data, Dalton is averaging 5.8 yards per play when opponents send four or fewer pass rushers, but that average jumps to 7.3 against five pass rushers, and 11.3 against big blitzes of six or more pass rushers. Unfortunately for Cincinnati, he might not get a chance to burn the Colts' blitzes. Indianapolis is only giving up 4.6 yards per play on big blitzes (as opposed to 6.8 yards per play with five rushers, and 6.4 with fewer than that). More to the point, though, they have only used big blitzes on 12 percent of opponents' pass plays. If we figure Dalton will get 40 dropbacks this weekend, then he'll probably only see four or five big blitzes all day. That handful of plays could be the difference between defeat and victory.

With all of that in mind, the more often Cincinnati can run the ball, the more likely their chances of winning. In particular, they need to keep giving the ball to Jeremy Hill, a lesson they had clearly learned by the end of the year. Over the course of the season, the rookie runner out of LSU split carries fairly evenly (222 to 168, to be precise) with Bernard. In the last three weeks of the season, though, that split jumped to nearly 3-to-1, as Hill got 70 carries to only 26 for Bernard. Hill has clearly been the better rusher this season, ranking sixth in both DYAR and DVOA.

The game plan for Cincinnati can be summed up in one word: patience. Pound away at the Colts, especially with Hill. When you must pass, don't try to force anything downfield, and avoid Vontae Davis; look for opportunities underneath the coverage, and target Greg Toler and Darius Butler.

And for god's sake, don't let Dalton turn the ball over.

WHEN THE COLTS HAVE THE BALL

The Colts led the league in passing plays (Andrew Luck was fourth among individual quarterbacks), so the focus will be on the Bengals' pass defense. Ironically, Cincinnati's strengths and weaknesses in pass defense are exactly reversed from those of their pass offense: they have no pass rush, but their coverage is excellent. Justin Houston led the NFL with 22.0 sacks this season, and J.J. Watt was second with 20.5. That means both players had more sacks than the Bengals as a team, and Cincinnati was next to last in Adjusted Sack Rate. Carlos Dunlap led the team with 8.0 sacks; nobody else had more than 3.0. The Colts gave up only 29 sacks this year (eighth-fewest) and were ninth in Adjusted Sack Rate, so we shouldn't expect to see Andrew Luck on the turf much this weekend.

The good news for Cincinnati is that their secondary has been excellent. In fact, you could make a case that Terence Newman, Leon Hall, and Adam Jones have been the best trio of cornerbacks in the NFL this year. That's a bold claim to make, especially given that all three are in their 30s, and none has ever made a Pro Bowl. But Newman (4.3 yards allowed per target on the games we've charted so far), Hall (7.2), and Jones (6.7) have all posted good to great individual numbers, and their cumulative effect on Cincinnati's defense has been even better. Cincinnati ranks first in DVOA on passes to No. 1 receivers, third on passes to No. 2s, and second on passes to all other wide receivers. They're fourth in coverage against tight ends to boot. Only running backs have given the Bengals trouble on pass plays this year; they rank 29th in coverage there.

Since Newman, Hall, and Jones have been so dominant, the Bengals have been able to practically shut down both sides of the field. Their defense had the best DVOA this year on passes to the outside of the field; and, likely as a result, they also faced the lowest percentage of throws to the outside. As a result, everything gets funneled into the middle of the field. So the Colts won't be able to count on out routes, corner patterns, or swing passes to win; they'll have to focus on slants, crosses, and posts. And, mind you, it's not as if the Bengals are soft up the middle; they were fourth in DVOA on passes to that region.

How much will that matter against Luck and the Colts? Well, Luck was 12th among qualifying quarterbacks in DVOA on passes to the outside, but 23rd on throws up the middle. However, the differences in results on throws to his two most common targets up the middle were striking. Throwing to Reggie Wayne up the middle, Luck went 18-of-35 for 191 yards with three interceptions; to T.Y. Hilton, Luck went 22-of-30 for 399 yards. Cincinnati doesn't need to worry about Wayne, but Hilton could kill them on middle patterns.

If the Bengals decide to blitz Luck, they had better bring the house. Luck averaged 8.4 yards per play against exactly five rushers.* That's better then he fared against four or fewer rushers (7.0), or against six or more (6.0). The Bengals, meanwhile, have given up 7.2 yards per play when they rush five. They have fared better with four rushers or fewer (6.2), and done much better when rushing six or more, giving up only 4.2 yards per play. That's not likely to matter much this weekend, though. Cincinnati has only blitzed opposing quarterbacks about 22 percent of the time this year. For the most part, they are content to sit back and play coverage. This partially explains their (relative) kevin vulnerability to passes up the middle.

Blitzes aside, we know that Luck is going to target Hilton (along with Coby Fleener and Dwayne Allen) on passes up the middle. Do they have any other options? Remember that Cincinnati's biggest problems in coverage have come against running backs. Well, it just so happens that Ahmad Bradshaw was second among running backs in receiving DYAR, and Dan Herron and even Trent Richardson have been effective receivers at times as well.

And speaking of Bradshaw and company, the other option for the Colts, obviously, is to run the ball, a tactic that has worked for Bengals opponents all year. In fact, it's almost impossible to beat Cincinnati without running on them. The Bengals have five losses and a tie this year, and in five of those games they've given up at least 147 rushing yards. The struggles for Cincinnati show up in almost every facet of run defense; they rank 23rd or worse in Adjusted Line Yards, Power Success, Stuff Rate, and Second-Level Yards. Only in Open-Field Yards are they even mediocre (ranking 12th), and that again speaks more to their secondary than to their front seven. Further, they rank 20th or worse in runs to all directions -- except, oddly, to the same direction where they fare best on the other side of the ball: the offense's right tackle, where they rank ninth.

Indy, though, may not be able to join that club. If anything, their running game might be even worse than their DVOA ranking (which is boosted by Luck's scrambles) would indicate. Richardson was one of the bottom-five running backs in rushing value this year. Herron and Bradshaw both had negative DVOAs as well. Their offensive line was actually middle-of-the-pack in most of our run-blocking numbers (except for Power Success, where they were 31st), but they were 29th in Open Field Yards, a sign that their running backs lack game-breaking speed (not that this is a secret).

Given the strengths and weaknesses of the Cincinnati defense, it only makes sense that the Colts will run the ball a little more often than they would against most opponents. Given the strengths and weaknesses of the Indianapolis offense, though, it also makes sense that in the end, the Colts will live and die by what Andrew Luck can do.

SPECIAL TEAMS

[ad placeholder 3]

On the whole, this is a very even matchup, with the two teams within one or two spots in the rankings in overall special teams DVOA, Bengals kickoffs, Colts kickoffs, and Colts punts. There are two big disparities, one advantage for each team. The Bengals have been great on punts this year, with Kevin Huber finishing fourth in gross average, fifth in net. Cincinnati's coverage teams have only allowed a 7.5-yard average on punt returns, tenth-best in the league. The Colts, meanwhile, have gotten very little from punt returner Griff Whalen, who is averaging 7.2 yards per return, with a long gain of just 22 yards.

Cincinnati basically gives that advantage right back, though, because they have clearly been the inferior team when it comes to kicking field goals. Mike Nugent is 0-for-3 on kicks from 50-plus yards this year, while going 10-for-12 in both the 30- to 39-yard range, and from 40 to 49 yards.

The DVOA numbers say neither team has been special on kick returns, but there's actually a dynamic returner on each team. For a good chunk of the season, Adam Jones was the leading the NFL in both punt returns and kickoff returns. (Between defense and special teams, this was probably Jones' best season since his days in Tennessee.) He wound up fourth in punt returns (averaging 11.9 yards) and second in kickoffs (31.3). Surprisingly, he didn't score a touchdown in either category, though he did reel off a 97-yard kickoff return in the Carolina tie. The Bengals' overall return rankings were dragged down by the radically inferior performance of Brandon Tate (9.7-yard average on punts, 22.1-yard average on kickoffs), who got about 40 to 45 percent of the return duties. Expect Jones to see more action here now that it's win or go home.

The only player who edged Jones in kickoff returns? He's on the other sideline: Josh Cribbs, who might be first player to lead the NFL in a major statistical category despite playing in only six games. After months on the shelf, the 31-year-old joined the Colts in November and proved he was far from washed up. He only returned 19 kicks this year, but his 32.0-yard average wasn't skewed by a big play or two; he has averaged at least 28.2 yards per return (on at least two kicks) in every game this season. He was a giant upgrade over Whalen, who only averaged 25.3 yards per kickoff return.

OUTLOOK

The Colts are 3.5-point favorites on most books, and considering they're playing at home, that means the two teams are basically a coin flip. Cincinnati's wild fluctuations in performance mean either team could win, by large or small margins. It could also come down to A.J. Green's health. For those of you in Las Vegas, assuming Green plays, this might be a case where Bill Simmons' mantra of "when in doubt, take the points" makes sense. For the rest of us, it's most likely that the Colts will be the team moving on to the Divisional round.

The headline here is the battle between rushing yardage leader DeMarco Murray and the NFL's best run defense of 2014, but there's a lot more going on below the surface. Like Saturday's NFC wild card game, Sunday's game also poses questions about whether a team's full-season performance is a better indicator than how it is trending going into the postseason.

WHEN THE LIONS HAVE THE BALL

There's certainly a reasonable argument to be made that the Detroit Lions offense would rate higher in DVOA if Calvin Johnson had remained healthy all season. But when you take out the games without Johnson (Weeks 6-8), the numbers don't change as much as you might expect. The Lions' offensive DVOA without those three games is -0.7%, which would be 17th instead of 19th.

Where the Lions are likely to have success passing the ball depends in part on whether the Cowboys decide to change up the usual way they use their three main cornerbacks. Our game charting data is not yet complete, but on the games we have charted so far, we have Orlando Scandrick with a 57 percent Sucess Rate and just 6.7 yards allowed per pass. Brandon Carr, on the other hand, comes out with 46 percent Success Rate and 10.2 yards allowed per pass. Nickelback Sterling Moore matches Carr's poor Success Rate but also matches Scandrick's fine yards per pass number.

When you consider that Brandon Carr is listed in the starting lineup as "LCB" (offensive right) and Scandrick is listed as "RCB" (offensive left), those charting numbers seem downright kooky in conjunction with the other Dallas splits we have on the team defense page.

  • The Cowboys excelled at covering "other" receivers this year, but were a dismal 29th against No. 2 receivers. They were average against No. 1 receivers.
  • The Cowboys were the worst defense in the league against passes on the offensive left, but ranked 10th against passes on the offensive right and had the best DVOA in the league against passes in the middle of the field. The problem on the offensive left is primarily about short passes; the Cowboys 20th in DVOA against passes that are listed as "deep left."

The numbers don't quite match because Scandrick isn't really playing right cornerback. When the Cowboys go nickel, Scandrick moves inside and Moore comes in to play right corner. Scandrick is doing a great job of shutting down whoever the opponent sticks in the slot; thus, Dallas has great numbers against "other" receivers and passes in the middle of the field. At the same time, Brandon Carr is getting burned plenty, and Moore is really getting killed on short passes, which is why his yards per pass allowed looks okay but his Success Rate (and the Cowboys' DVOA against passes listed as short left) is poor.

The Cowboys can't be wasting Scandrick on the Lions' slot receivers because unless the Lions are moving Johnson or Golden Tate into the slot, they probably are not going to throw there. Detroit was one of only two offenses in the league this year that threw less than 10 percent of passes to "other" receivers. (Chicago was the other.) That might be Eric Ebron in the slot, but despite all we heard about Ebron's athletic talents, he struggled like most rokie right ends do, with -30.0% receiving DVOA and just a 52 percent catch rate. The Cowboys need to make sure Scandrick is covering Tate or Johnson and not being wasted on Corey Fuller.

Of course, Tate and Johnson will end up in the middle of the field anyway because of the types of routes they run. It's a strength of the Lions offense, which ranked No. 4 in DVOA on short middle passes and No. 6 in DVOA on deep middle passes. As noted above, the Cowboys were fantastic against passes in the middle of the field, ranking No. 1in DVOA against deep middle passes and No. 2 (behind New England) against short middle passes -- although these ratings are in part caused by some interesting splits on interceptions. The average NFL team threw four picks this year listed as "middle." Detroit had only two, while the Dallas defense led the league with ten, including five in just the last three weeks.

The Cowboys are more likely to depend on interceptions than sacks, since they have very little pass rush. The Cowboys ranked just 29th in Adjusted Sack Rate this year, and that got even worse on third and fourth downs where they had just 3.5 percent Adjusted Sack Rate. In their season-ending four-game winning streak, the Cowboys only had two sacks on third or fourth down, both of Mark Sanchez in Week 15.

For the most part, the Detroit ground game will be there to provide balance, not to really move the offense along, and we won't see too much of it. The Lions ran only 36.3 percent of the time; among teams with winning records, only Indianapolis ran less often. Although as bad as the Lions have been running the ball this year, the Cowboys haven't been much better stopping it. The best place for Detroit to find running room might be around right end, where the Lions ranked 10th in Adjusted Line Yards while the Cowboys were just 29th on defense.

The best use of the running game for Detroit might be in third-and-short situations, where they've had good success and the Cowboys defense has struggled. The conversion rates are similar: 65 percent (15th) for the Lions offense and 67 percent (20th) for the Cowboys defense, but the Cowboys also have allowed a few big runs by teams looking for just one or two yards. Seven times this year, running backs gained six yards or more against the Cowboys on third-and-1 or third-and-2.

The Lions ranked fifth in DVOA on third downs this season, while the Cowboys were just 28th in defensive DVOA. However, that Detroit rating is entirely built on early-season success. Detroit had an insane 56.0% DVOA on third downs in Weeks 1-9, with 45 percent Success Rate and 8.1 yards per play pumped by seven plays of 35 or more yards. Since Week 10, Detroit has -7.4% DVOA on third downs (18th in NFL), with 37 percent Success Rate and just 5.7 yards per play with just one play over 35 yards.

WHEN THE COWBOYS HAVE THE BALL

This is where we're supposed to be seeing strength against strength, except one of the two strengths hasn't been quite so strong the last few weeks. The Detroit defense has declined significantly in the second half of the season.

Defensive tackle Nick Fairley sprained his knee against the Falcons in Week 8 and has not played since. With that personnel change, you might expect the decline to have come primarily against the run. Instead, it's been the opposite -- the Lions have fallen apart on pass defense but are still stalwart against the run. The Lions were third in the league with -29.8% run defense DVOA in Weeks 1-9, then first in the league with -33.0% run defense DVOA in Weeks 10-17. Their Adjusted Line Yards allowed also stayed virtually the same. So the biggest battle of strength vs. strength is ready to go.

Dallas Offensive Line vs. Detroit Front Seven
Team ALY Rk RB Yd/Run Power Rk Stuffed Rk 2nd Lvl Rk Op Field Rk
Dallas offense 4.39 1 4.85 76% 4 18% 11 1.37 2 1.10 2
Detroit defense 2.83 1 3.17 63% 15 25% 3 0.86 1 0.49 5

By the way, as good as the Dallas offensive line was this season, they aren't as strong historically as the Lions defensive front seven has been. Only three teams since 1996 had lower defensive ALY allowed than this year's Lions: Minnesota in 2006, San Diego in 1998, and Baltimore in 2000. The Cowboys' ALY on offense doesn't even rank them among the top 50 teams since 1996.

Of course, here at Football Outsiders we believe strongly that passing is almost always more important than running and pass defense is almost always more important than run defense, which brings us back to the decline of the Lions pass defense. Detroit led the league with -16.0% pass defense DVOA in Weeks 1-9, but in Weeks 10-17 they ranked 23rd with 8.7% DVOA. The problem is particularly bad on third downs:

Detroit Pass Defense, Weeks 1-9 vs. Weeks 10-17
  Weeks 1-9 Weeks 10-17
Down DVOA Rk Suc Yds DVOA Rk Suc Yds
1st Down -5.7% 4 49% 6.22 13.2% 16 52% 6.40
2nd Down 4.6% 14 43% 5.85 2.5% 23 43% 5.78
3rd/4th Down -61.6% 1 28% 4.80 10.6% 24 43% 5.84

(Brief aside: Yes, the Lions' pass defense DVOA ranked nine places lower in the second half of the year despite being slightly better. For some reason, pass defense around the NFL on second downs was kind of nutty crazy good in the second half of the season.)

Does this have anything to do with the Fairley injury? Well, the Lions Adjusted Sack Rate did drop from 7.5 percent in the first half of the season (eighth in the NFL) to 5.7 percent in the second half (29th). However, they were actually bringing more pressure overall; it just wasn't taking down the quarterback. According to ESPN Stats & Information charting data, in the first half of the season, the Lions brought pressure on 29.4 percent of pass plays, fourth in the NFL. In the second half, they brought pressure on 31.3 percent of pass plays, second only to Arizona.

So those numbers suggest the problems relate to the Lions' linebackers and defensive backs more than the defensive linemen. Specifically, it looks like the biggest portions of the decline came in covering No. 1 receivers and covering running backs in the passing game.

The Lions allowed 7.3% DVOA and 73 percent catch rate to running backs in Weeks 1-9. They allowed 22.0% DVOA and 85 percent catch rate to running backs in Weeks 10-17. This is very small sample size -- 22 plays -- but the Lions allowed 61 yards and one first down on 11 third-down passes to running backs through Week 9, then 134 yards and five first downs on 11 third-down pases to running backs after Week 10.

The Lions weren't bad against No. 1 receivers after midseason, just not as fabulous as they were in the first half of the year. The Lions allowed -56.1% DVOA to opposing No. 1 wideouts with 48 percent catch rate through Week 9. From Week 10-17, that became -3.7% DVOA and 59 percent catch rate.

Unfortunately, we don't have enough Detroit charting from the second half of the season complete to really be able to say whether there's been a specific decline from one of the Lions' cornerbacks. The stats based on location on the field suggest that Darius Slay has not been playing as well in the second half of the year, although the Lions tend to use deep safeties a lot so we don't want to strictly blame deep passes on cornerbacks. Nonetheless, the Lions have declined against both short right and deep right passes.

Detroit Pass Defense, Weeks 1-9 vs. Weeks 10-17
Weeks Left DVOA Rk Middle DVOA Rk Right DVOA Rk
Weeks 1-9 7.1% 22 -23.4% 2 -20.9% 5
Weeks 10-17 -20.3% 9 1.5% 13 4.1% 26

While the Detroit pass defense has been struggling in recent weeks, the Dallas passing game has been on fire. At midseason, the Cowboys ranked 14th in pass offense DVOA. Since Week 10, the Cowboys are second, just a couple of tenths of a percent behind Green Bay. And nobody has been hotter than Dez Bryant, who is getting targeted less often but with far more efficiency.

Dez Bryant Weeks 1-9 vs. Weeks 10-17
Weeks Tgt/G Yd/G TD/G DVOA Catch Rate
Weeks 1-9 (9 games)* 10.0 78.6 0.7 5.1% 58%
Weeks 10-17 (7 games) 7.1 97.9 1.4 68.5% 76%
*Includes four DPIs.

SPECIAL TEAMS

[ad placeholder 4]

Things are not quite as bad for Detroit as the table above makes it seem. Of course, the Lions had massive problems in the kicking game early in the season, with Nate Freese and Alex Henery combining to go just 4-of-12 on field goals. But things have been better since Matt Prater took over in Week 6, as he's been 21-of-26. By our measures, he's been worth -1.85 points after adjusting for weather/domes, which is still below average but very different from Freese (-9.7) or Henery (-8.0). Taking out Freese and Henery's field goals would improve Detroit's special teams DVOA to -2.1% for the season, 21st instead of 31st.

However, the rest of Detroit's special teams have been nothing special either. Sam Martin has been good on kickoffs and very good on punts -- we have him worth an estimated 6.8 points of field position on gross punt value, fourth in the NFL -- but the coverage teams are lousy which cancels that out. Jeremy Ross has been a mediocre return man.

The Cowboys are more likely to make a big play on special teams. Dwayne Harris hasn't had a great year as a return man this year, but we know he made some big plays in 2013, so he's more dangerous than this year's numbers indicate. (Harris also leads the team with 12 special teams tackles.) Dan Bailey has been very good on field goals over the last two seasons; the Cowboys' kickoff value for this year is primarily in strong coverage, with Bailey's kick distance rating as average.

OUTLOOK

So, how do we judge these teams? Should we be only thinking of the Lions offense in the weeks when Calvin Johnson was healthy? Should we be only thinking of the Lions special teams in the weeks when Matt Prater was the kicker? And how much does it really mean that the Detroit pass defense as been in serious decline since the start of November while the Cowboys passing game is hitting on all cylinders?

On one hand, we keep doing research that shows that "late-season momentum" doesn't seem to predict playoff results as well as just using stats from the entire 16-game regular season. On the other hand, we have common sense. Certainly when it comes to the Lions defense, the idea that Detroit had the best defense in the league seemed a little weird in the first half of the season. We knew the defensive line was good, but there were so many questions surrounding their secondary. The second-half performance seems to match the personnel involved here more than the dominating first-half performance.

However, we don't have to depend solely on second-half trends to give us evidence that the Dallas offense seems to be better than the Detroit defense. Use stats from the whole season, and the Dallas offense still comes out a little better than the Detroit defense. Look at the trends from the last few weeks, and the Cowboys come out a lot better. Whichever of those statements you believe to be true, if you add the Cowboys' advantage on offense to their special-teams and home-field advantages, they are the clear favorites in this contest.

An added wrinkle suggesting a Dallas victory: the Lions may be too consistent to put together the huge performance they might need to win on the road. Only Houston had a lower overall DVOA variance than the Lions this season. Detroit also had the fourth lowest variance on offense and eighth lowest on defense. The Lions didn't really have a game where everything fell apart, but they didn't really have a game where everything suddenly clicked, either. And they will need a game like that to beat the Cowboys if Tony Romo and Dez Bryant continue to play as well as they have over the past two months.


STATS EXPLAINED

DVOA (Defense-adjusted Value Over Average) breaks down each play of the season and compares it to the NFL average based on situation and opponent. You'll find it explained further here. Since DVOA measures ability to score, a negative DVOA indicates a better defense and worse offense, and a positive DVOA indicates a better offense and worse defense.

Team DVOA numbers incorporate all plays; since passing is generally more efficient than rushing, the average for passing is actually above 0% while the average for rushing is below 0%.

SPECIAL TEAMS numbers are different; they represent value in points of extra field position gained compared to NFL average. Field goal rating represents points scored compared to average kicker at same distances. All special teams numbers are adjusted by weather and altitude; the total is then translated into DVOA so it can be compared to offense and defense. Those numbers are explained here.

Each team is listed with DVOA for offense and defense, total along with rush and pass, and rank among the 32 teams in parentheses. (If the DVOA values are difficult to understand, it is easy to just look at the ranks.) We also list red zone DVOA and WEIGHTED DVOA (WEI DVOA), which is based on a formula which drops the value of games early in the season to get a better idea of how teams are playing now (explained here).

Each team also gets a chart showing their performance this year, game-by-game, according to total DVOA. In addition to a line showing each game, another line shows the team's trend for the season, using a rolling average of the last five games. Note that even though the chart appears in the section for when each team has the ball, it represents total performance, not just offense.

1 Re: Sunday Wild Card Playoff Preview 2015

The performance of Cincy corners is really unbelievable. As a Dallas fan, I was around for Terence Newman's best YPA and success rate years in the ~2005-07 range, and I thoroughly believed he was done after watching him be quantitatively one of the NFL's worst corners in 2010 and 2011. Pacman's charting results never got quite as high or quite as low, but he was similarly unproductive when he left Dallas.

Now, they are three years older and yet are somehow 2/3 of the NFL's top cornerback corps (along with Hall, that's 3 former first round picks, although from 3 different teams). I love advanced CB metrics, both from Football Outsiders and elsewhere, but I think a case study like this really hammers home how scheme- and situation-dependent the results can be. Tough to definitively rank guys outside of the very good (e.g. Revis) and the very bad (e.g. Cortland Finnegan?).

(As a minor nit with the article, I believe Newman and Leon Hall have both made Pro Bowls, although likely as replacements, not initial top vote-getters)

2 Re: Sunday Wild Card Playoff Preview 2015

A comment on the Colts punt returns. Whalen has not been the returner since Cribbs joined the team. The eye test has Cribbs being a better returner than Whalen in that department.

Any insights on the Colts rushing defense? The only time they really got gashed was the Patriots game, and I think that was because they were more concerned with Brady. Generally, the Colts defense has been reasonable against the run, forcing the opponents QB to beat them. This worked well against the AFC south and the other lousy QBs they faced, but got them lit up by good QBs. The good QBs would go at Toler as mentioned, and exploit the poor coverage skills of the Colts' inside LBs.

Ultimately, though, I think this game comes down to which QB makes more dumb mistakes and loses the game for his team.

3 Re: Sunday Wild Card Playoff Preview 2015

The lions seem like the worst possible matchup for Dallas to me. I could see the Cows making a run if they get past this one. Johnson has single-handedly beat the Cowboys in the past, and the defensive line poses enough of a threat to neutralize the Dallas offense. The reversal of Suh's suspension looks critical to me

8 Re: Sunday Wild Card Playoff Preview 2015

Agree. The Cowboys like to stick to the run even when it's not producing much for them, which is fine and helps in the Time of Possession game, but puts more of a burden on your passing game to pick up long third downs. The worst case scenario for the Cowboys is they go 3-and-out on their first few drives after running on 1st and 2nd down for no gain and having some bad luck on long 3rd down passes, while meanwhile Detroit gets a few big plays to Tate and Johnson and suddenly they have a double-digit lead.

While I don't know if this is a LIKELY scenario, it's certainly a very POSSIBLE one given Detroit's defense, and would have seemed much less possible against other NFC teams, particularly Green Bay.

4 Re: Sunday Wild Card Playoff Preview 2015

It's not crazy to envision a scenario where Suh pulls a JJ Watt and dominates the interior of a great offensive line.

The Cowboys are almost certainly expecting their center/guards to play Suh to a draw. If they do NOT then things get interesting.

When the Lions have caused problems for Green Bay it's not that Suh gets big sack numbers for himself it's him blowing up the middle, Rodgers having to move too soon and one of the Detroit ends or linebackers cleaning up.

6 Re: Sunday Wild Card Playoff Preview 2015

I want the Lions to win, not because I want to play them, but I'd rather play Carolina or Arizona before going to Seattle and losing. I still think we'll beat Dallas if they win before going to Seattle and losing. I don't see Detroit beating Seattle for an NFC Championship rematch, if they do manage to beat Dallas.

7 Re: Sunday Wild Card Playoff Preview 2015

I forgot about reseeding, which makes a Lions win even more appealing to Packers fans. Yeah the Packers will be solid favorites over the Cowboys in Lambeau, but a Cowboys victory would only be a very mild upset, in my view, because they can keep the ball away from Rodgers in his home field advantage. I think the Cowboys clearly match up best in CenturyLink, whereas I don't think the Lions could score more than 10 points in Seattle, at least until the game was out of reach. I think the Lions defense is overrated, truthfully. Hell, the Vikings had 3 drives of 75 yards or more against the Lions in Detroit, in a December game that meant a lot. I really want to see the Cowboys play in Seattle again, because I think they are only team with an offensive line which can physically challenge the Seahawks' defense in Seattle.

9 Re: Sunday Wild Card Playoff Preview 2015

I wouldn't be shocked by Dallas beating Green Bay either, and I would like to see their line against a fully healthy Seattle defense in Seattle too. Of course being a homer I'd much rather see the improved GB line in Seattle again.

I know they lost in Buffalo, which really does have a great defense. While they did get some pressure on Rodgers, which I think influenced at least one of the interceptions, the strip-sack safety at the end was the only time they brought him down. The Packers also ran the ball well, in fact it was their best rushing game by DVOA, and while I'm sure some of that is adjustment I think they had a pretty good rushing VOA too. Lacy only got 15 carries, but he had the 2nd most yards by a running back against them and was at 6.5 ypc. Lacy is good, but there were some holes for him to hit.

I'm with you that the Lions are over rated. They are good, but I don't think they are as good as the numbers say. Green Bay did a pretty good job of pushing them around too. Yes I know they did have 6 shots on goal to go and failed, I'll get to that.

I don't think people realize how much better Green Bay's line has gotten as the year progressed. Sitton made 2nd team all pro, and I think he was snubbed. Linsley is true mauler and I think one of the better centers in the league already. Bahktiari is better than most left tackles, I'd put in him the 8 - 12 range. Bulaga is one of the top 5 right tackles in the league. Lang just got done stonewalling Suh and has been one of the better guards in the league all year as well.

FO has them 8th for rushing and 13th for passing stats, and they were in the 20's in both still after 5 games and I think were still like 18th in pass pro after week 8. Some of that was injuries earlier in the year, but even the injuries were generally short and quite manageable. That helped a lot. They have been playing like one of the best lines in the league over the 2nd half of the season. They aren't as good as Dallas (1st and 17th) and I know there are issues with adjusted line yards and adjusted sack rate for rankings, but they do give a ballpark. That pass protection for the Packers has been with a gimpy Rodgers for several games.

Now the Packers do still have some issues with some things. The power and stuffed numbers measure those area, but those too have improved recently. Also some of the stuffed issues are due to the love of the pitch play that McCarthy has in situations where the defense knows it's coming, and to a running back who isn't the fastest in the world. I know these stats also relate more to what you, and I as well, tend to think of when we think about an offensive line dominating a game, and Dallas is clearly better. Which is why I would enjoy seeing them against Seattle as a consolation if they beat GB.

I just think people overlook what GB has done because they were a shaky unit to start the season. When your planned starting center goes down in the 3rd preseason game, and the rookie replacement doesn't have his first game snap with the starting QB until the first game of the season, you expect some growing pains. You also expect improvement when they aren't having to play the injury shuffle all season long.

10 Re: Sunday Wild Card Playoff Preview 2015

The Packers 0-line started the year looking like the soft units that have not been unusual in Rodgers era, but they ate their spinach at some point, and they can now square up and slug it out. They aren't the brass knuckle crew that resides 1000 miles due south (and that also can bully anybody when away from their residence), but they'll more than do on most days, and especially so at home.

12 Re: Sunday Wild Card Playoff Preview 2015

The other thing is that while Stafford is a middling quarterback, he's high variance, and tends to have his biggest games against below average defenses. I think he'll have to, because the Dallas offensive line really scares me...they're good enough to beat the great Detroit dline when they're on.

11 Re: Sunday Wild Card Playoff Preview 2015

As a Bengals fan, who lives on the edge of Colts country. I have seen every one of both teams games this season.

There's a lot of history, any number of signs and omens that bode ill for the Bengals. None of that means anything. Every season, every team is not really the same as it was the previous season. The Marvin Lewis playoff losses have one major thing in common. The other team was better overall, and played better than day.

This series of failures might get into Any Dalton's head, that's the one possible way in which all this meaningless history might affect this game.

Dalton vs. Peyton Manning:Well they have the same job, the comparison ends about right there. Just for fun, compare their numbers in their first three playoff starts though.

Manning: 1st 3 playoff games:50 comp 150 att, 47% 1TD 2INT
Dalton: 1st 3 playoff games:70 comp 123 att 57% 1TD 6INT

Both were 0-3 of course.

When I watch Dalton play I see periods where his lack of velocity and sometimes terrible decision making lead me to believe the Bengals need to look for another answer. Other times he looks efficient, capable of making the throws that he needs to, athletic enough to pick up some yards on key plays. In fact he reminds a great deal of a former Colts QB...

No not Manning, I'm not completely stupid. Jim Harbaugh, my father and I had a rule, you could refer to Harbaugh as 'good';but you weren't allowed to use any adjectives to go with good. Never VERY or REALLY good, just good. Dalton can be that kind of good. 3 playoff games don't define a career.

Nevermind the fact an NFL QB plays around 3% of his teams minutes. This isn't tennis or golf kids. Playoff wins and championships, like regular season games are contested by 22 players at a time, and had Rogers/Brady/Manning/Luck/whoever started for the bucs, raiders, jets or jags this year, those teams would have still sucked.

Now the Browns/Rams/Cards on the other hand...

20 Re: Sunday Wild Card Playoff Preview 2015

Am I missing something? How did you get 50 comps in 150 atts = 47% for Manning?
Too lazy to check the stats, but I can believe the 47%, but not the 50/150... that's just insanely poor.

And really, Manning's 1st playoff game was a close loss to eventual SB runner-ups Titans (let's estimate a 50% comp rate), and his second playoff loss was an OT game in which his D allowed over 200 rushing yards to a nobody (can you pass for less than 50% and still tie a playoff opponent?)--can't quite align those two games with a 50/150 performance. Was the next one the 41-0 waxing by the Jets? That might have skewed the 3-game data somewhat, and in that game, Edge James racked up a whopping 13 rush yards on 9 attempts (or was it 9 yards on 13 atts?) which will negatively affect other offensive stats. Did Dalton ever have such awful rush support? Or a D that allowed over 200 yards to the immortal Lamar Smith?

Not sure the small data-set comparison (in a vacuum) passes the sniff test.

15 Re: Sunday Wild Card Playoff Preview 2015

Re: Detroit-Dallas. Way to force the analysis to match the narrative. You run all the stats, then say the stats are crap, everyone knows Dallas has been awesomesauce, kthnxbai.

Might come true, but that's a crap way to reach the conclusion.

16 Re: Sunday Wild Card Playoff Preview 2015

However, we don't have to depend solely on second-half trends to give us evidence that the Dallas offense seems to be better than the Detroit defense. Use stats from the whole season, and the Dallas offense still comes out a little better than the Detroit defense. [I]f you add the Cowboys' advantage on offense to their special-teams and home-field advantages, they are the clear favorites in this contest.

How is this saying the stats are crap? The stats say that Dallas leads Detroit by 9.4% in DVOA (or slightly less if you discount Detroit's earlier FG troubles), and add to it 17% for home-field advantage and you get their conclusion that Dallas is the clear favorite.

21 Re: Sunday Wild Card Playoff Preview 2015

Quote the first part of the section:
"On one hand, we keep doing research that shows that "late-season momentum" doesn't seem to predict playoff results as well as just using stats from the entire 16-game regular season. On the other hand, we have common sense. Certainly when it comes to the Lions defense, the idea that Detroit had the best defense in the league seemed a little weird in the first half of the season. We knew the defensive line was good, but there were so many questions surrounding their secondary. The second-half performance seems to match the personnel involved here more than the dominating first-half performance."

1. We don't believe in momentum, except when our pre-conceived opinions agree with a momentum narrative. In which case, we believe in momentum.
2. Our stats disagree with our preconceptions. Therefore, we disregard our stats.
3. Our data says that full-season analyses are more robust than partial-season analyses. Except here, where we want to believe the partial-season result more, because reasons.

This would be fine for ESPN, but FO is supposed to be an analytics site. If your stats are misleading, defend why. Show your work. Why don't you believe, in this example, what you generally believe everywhere else?

I don't have any problem with the conclusion that Dallas is better than Detroit. But that argument was irrelevant towards demonstrating that point.

26 Re: Sunday Wild Card Playoff Preview 2015

I don't know, guy. He seems to be saying that whether you want to use the "eye-test" that suggests some late-season momentum (even if their metrics don't (yet) seem to indicate that such things are valid), or go by what seems to be concrete measures (i.e. the full 16-game season stats), Dallas should be favored.

24 Re: Sunday Wild Card Playoff Preview 2015

Well, it just so happens that Ahmad Bradshaw was second among running backs in receiving DYAR...

And speaking of Bradshaw and company, the other option for the Colts, obviously, is to run the ball.

Herron and Bradshaw both had negative DVOAs as well.

Why does this matter? Bradshaw is on IR.
