Bill Connelly takes a look at what we can learn from defensive box score stats and general rates of havoc.

We talked about a team "peaking at the right time" in this week's DVOA analysis. Now it's time to talk about one trending in the other direction.
Since their Week 8 bye, the Houston Texans have had just two above-average DVOA game scores: against the Bears in Week 10, and against the Titans in Week 13. They've managed to win a good majority of those games anyway because (a) they weren't exactly facing a murderer's row outside of New England and (b) they had some fortunate bounces in close games. For instance, the Justin Forsett "touchdown run" against the Lions on Thanksgiving.
While the offense has gotten a majority of the blame for this -- and trust me, we'll get to them by the end of the article -- Houston's defense has also fallen off. In those six games after the bye where Houston has posted a negative total DVOA, the highest defensive DVOA the Texans have achieved is -6.6%. If that doesn't sound too bad to you, remember that these relatively mediocre ratings are despite J.J. Watt having one of the greatest defensive seasons in NFL history.
It was shooting fish in a barrel to predict Houston's defense to regress after their tremendous improvement in 2011. What has been surprising is not that it happened, but how it has happened. Watt has been spectacular, and Kareem Jackson has blossomed into a capable, if not outstanding, second cornerback. The run defense has held up very well despite Brian Cushing's injury and Houston's continued "ignorance is bliss" strategy when it comes to upgrading at nose tackle.
Instead, the main issue has been the lack of pass rush outside of Watt. The outside linebackers, in particular, have struggled to get to the quarterback. Connor Barwin, of the 11.5 sacks last season, is stuck on four in 2011. (However, Barwin does have 16 quarterback hits through Week 14 -- well on pace to match his total of 19 from 2011, so he's not a totally lost cause.) Brooks Reed missed most of the last few weeks with a groin injury, but he has added just 2.5 sacks. First-round pick Whitney Mercilus has accumulated six sacks in (mostly) situational play, but has problems staying on the field at this point because he can't keep contain on the outside. Cushing's absence is actually felt more here than anywhere else -- he's one of the best blitzers in the NFL from the inside linebacker spot. Without him, the Texans have had a harder time generating pressure in their dime and situational nickel packages.
In coverage, both of 2011's free-agent heroes, Johnathan Joseph and Danieal Manning, have regressed. Joseph has battled through a groin injury for most of the year, so he at least has that to fall back on. Manning spent most of this day biting on play-action fake after play-action fake as the Texans spent their time trying to limit Adrian Peterson. Another silent killer has been the lack of consistency the Texans have received from the sixth defensive back in their dime packages -- the third safety. Quintin Demps has been cover-your-eyes awful this year, and was the main culprit on Donte' Stallworth's long touchdown catch in New England. The Texans have mixed in Troy Nolan and, in this game, Shiloh Keo, to about the same level of success. (Watching Keo come on a blitz is almost comical -- he's practically playing pattycake with offensive linemen.)
In short, the Texans have become completely reliant on their superstar to win on defense over the last two months. Without Watt's pass-rushing success, Wade Phillips' defense is imminently beatable. Houston's chances of avoiding a one-and-done in the playoffs are going to be riding on Watt's shoulders unless Phillips can find the right tweak -- and he's had two months now to find a solution.
It may not be coming.
Oh, right, the actual game itself! It was a bloodbath.

The only number that significantly changes when we change VOA to DVOA is Minnesota's offense, which moves up from -10.4% to 9.5%.
Gary Kubiak gets this for his cumulative efforts in the third quarter. Down 13 with 7:58 in the third quarter, Kubiak elected to punt on fourth-and-6 from the Minnesota 41. Then, when first-and-goal presented itself roughly six minutes later, Kubiak ran the ball just once. Matt Schaub was sacked on third down, removing the Texans from the range where they could conceivably go for it on fourth down, and the game was effectively over.
The Texans' passing woes aren't so hard to believe once you figure out that Schaub completed just two of nine passes to his non-Andre Johnson wideouts. In fact, Texans Third Receiver, a generic blend of rookies DeVier Posey and Keshawn Martin, with a sprinkle of undrafted free-agent pickup LeStar Jean, has caught 51 of the 125 passes in his direction this year. Kevin Walter has seen his catch rate tumble to 60 percent, which is the lowest it's been since he became a full-time starter in 2007. Houston's passing game needs to be focused more on its tight ends to be successful, and Minnesota was constantly able to hurry Schaub in this game, leading to a lot of checkdowns on third-and-long because the Texans had problems staying on schedule. As for why that was...
Here is a list of numbers, let's see what they have in common.
-27.3%, -0.8%, -21.9%, 50.1%, -21.4%, 0.0%, -11.7%, -67.1%.
A) my chances of winning the lottery (where was I on that 50.1% day?)?
B) the APR finance rates on my last eight vehicles after I installed a virus on my car dealer's computer?
C) the rushing offense DVOA scores, game-by-game, for the Texans since Week 9?
It was a given that Houston's run attack would lose something when the salary cap forced the departures of right tackle Eric Winston and right guard Mike Brisiel. The Texans filled those voids with a bunch of possible options. Rashad Butler and Derek Newton would battle it out at right tackle, and Houston spent third- and fourth-round picks on Brandon Brooks and Ben Jones to try and unseat Antoine Caldwell.
Outside of losing Butler for the season, nothing has settled yet. Newton has been so bad that Ryan Harris, who was signed just before the start of the season, has taken about 35 percent of the playing time. Caldwell was horrendous before getting replaced by Jones. Jones and Brooks are now splitting time at right guard, and have both been rather inconsistent.
In this particular game, outside of some notable Newton blowups and a hilariously blown chop block by left guard Wade Smith, most of the missed blocks came from the skill players. Garrett Graham has absorbed Joel Dreessen's snaps this season, and while he's a capable receiver, he's not anywhere near Dreessen's level as a blocker. Owen Daniels has never been a good blocker. Everson Griffen and Jared Allen were able to regularly get penetration and keep Arian Foster from getting any room on the edge. Kevin Williams won his individual matchup with Chris Myers handily.
That's not to say that Foster hasn't regressed as well this year -- he clearly has. His balance going through the offensive line has been shaky and he's not generating anywhere near as many missed tackles as he did in 2011 or 2010.
But the problems in the Houston run game start up front.
