What Does the NFL Draft Really Produce? (Part I)

by Scott Kacsmar

This is the week when analysts rush to grade the NFL draft that just happened before any of the players have even played a down. We are going to do something very different here today by looking only at drafts where every player has retired from the NFL, ensuring complete career data. I had been sitting on this idea for four years, but this offseason was finally the time to complete it.

With the recent retirements of Peyton Manning, Charles Woodson, and Matt Hasselbeck, every player drafted before 2000 is now retired. In 1994, the NFL made important changes by introducing a salary cap and shrinking the draft to seven rounds like it is today. Even a draft as recent as 1992 had 12 rounds, if you can believe it.

By studying the 1994-1999 drafts, which saw a total of 1,459 players drafted, we have the first six examples of what a seven-round NFL draft really produces. Today, with the advent of "Draft Twitter," there are more supporters and detractors of draft prospects than ever before. Late-round picks that would have garnered little interest in the past have a new glimmer of superstar hope because "that guy I follow had him as a second-round pick for two months." Sifting through the takes can be more troublesome than warranted now. While so many current draft grades are favorable and fan expectations are sky-high for most prospects, we know that within a few years many of these players will turn out to be average at best. There just cannot be that many studs in one draft. We know several first-round picks will bust, and a few late-round gems will surface. Getting two starters and two contributors is a great haul in theory, but we will have to see what the data says below.

Judging player value is never easy, especially for non-skill positions, and in this timeframe we are lacking snap data, which FO only has back to 2002 right now. A mid-round pick that does not start games, but plays on special teams and is a multi-year backup, can be valuable to a team. Only 22 players on the 53-man roster can start in a given week, but the benefits of a good backup are hard to quantify. How do we know the player is good if he never has to see the field? A team keeping a player around seems like a good argument for his worth, but even Will Blackwell lasted five seasons in Pittsburgh. Victor Allotey, a seventh-round guard drafted in 1998, was the study's most unique example, lasting six seasons (three each with Buffalo and Kansas City) despite never playing a regular-season game. Some fans on Reddit even believed him to be a homeless ex-player. Needless to say, Allotey never left much of an impact despite his lengthy career.

So while we are heavily using games played and games started here, there are obvious limitations to the usefulness of that data. Years of experience were also collected, though if a player was cut or traded during the season, then that still counted as a full season with that team. This also includes Allotey-esque seasons where the player may not have played a single game. For the most part, years of experience were coordinated with the data at NFL.com, except for obvious cases of difference such as Walter Jones not playing in 2009 or a data error with Bernard Williams (banned after failing 15 drug tests) making a comeback in Philadelphia that never happened.

Weighted career Approximate Value (AV) from Pro-Football-Reference was also collected for this study. Like any stat, it is imperfect, but it makes a grand attempt to quantify every player-season at each position, and the results are more than respectable. The top players in AV in this study are Peyton Manning (177), Ray Lewis (160), Derrick Brooks (144), Marshall Faulk (133), Marvin Harrison (124), Randy Moss (123) and Warren Sapp (120).

We will start with a broad view of the draft results before chopping things down into smaller bits. Supplemental draft picks were not included. Player-for-player trades were not considered either, though I am not sure there were any Manning/Rivers-level deals in any of these years anyway.

Draft Results: By Career

It is often said that the average NFL career lasts three to four years. The NFL Players Association has quoted an average of 3.5 years, though some question their methods. It is reasonable to think careers are getting shorter today than they were in the period of this study, but my results are much closer to the NFL's proposed figure of 6.0 years from 2011. Naturally, adding in the numerous undrafted players that try to make a team each summer would bring down the average, but can you really call that a career if you never make the final cut? An average career length of five-plus years looks very accurate for drafted players.

NFL Draft: Average Career Length
Draft Players Years of XP Games Starts AP1 Pct. PB Pct. CarAV
1994 222 5.8 68.1 37.6 9 4.1% 26 11.7% 18.5
1995 249 5.4 60.8 35.0 12 4.8% 28 11.2% 16.6
1996 254 5.6 66.6 40.1 17 6.7% 33 13.0% 19.3
1997 240 5.6 65.7 37.0 13 5.4% 24 10.0% 18.1
1998 241 5.7 64.6 39.8 11 4.6% 28 11.6% 19.0
1999 253 5.7 63.8 35.1 10 4.0% 25 9.9% 16.8
TOT 1459 5.6 64.9 37.4 72 4.9% 164 11.2% 18.0

In terms of average games played, the number is a tick under 65, or the equivalent of just over four seasons. That is more in line with the number I was used to hearing for average career length, but that is from a games played perspective only.

The columns for first-team All-Pro (AP1) selections and Pro Bowlers include how many players earned those honors and are not the total number of honors each draft accumulated. The highest individual honor one can receive, a bust in the Pro Football Hall of Fame, is something that could take decades to figure out a percentage for from these classes. Currently, just nine of the 1,459 players are inducted (0.62 percent), but look for Peyton Manning, Charles Woodson, Ray Lewis, Randy Moss, Terrell Owens, Alan Faneca, Brian Dawkins, Champ Bailey, Tony Gonzalez and perhaps a few more to at least double that amount. Ultimately, each draft class from 1994-1999 should have two to five inductees.

Regardless of current Canton busts, the 1996 draft is the cream of the crop from this era, with the highest average of starts and AV, and most individual honors (116 Pro Bowls and 43 All-Pros). It had the rare occurrence of a wide receiver going No. 1 overall (Keyshawn Johnson to the Jets), leading arguably the best wide receiver class ever with Terrell Owens, Marvin Harrison, Terry Glenn, Muhsin Muhammad, Eric Moulds, Joe Horn, Eddie Kennison, Bobby Engram, and Amani Toomer all surpassing 500 receptions and 7,500 receiving yards. (In a few years, 1996 vs. 2014 wide receivers should be a great debate.)

The 1995 and 1999 drafts were statistically not as impressive, though 1995 did see a few key injuries derail incredible careers, including Terrell Davis. Tony Boselli was another player on the fast track to Canton, and he really started the amazing run of offensive tackles that happened in this era with Jonathan Ogden, Orlando Pace and Walter Jones following in his footsteps. That run of talent likely led to the idea that tackles are "safe" picks at the top of the draft, and nearly-certain 10-year players. Then the likes of Robert Gallery and Jason Smith came around, along with more recent disappointments such as Matt Kalil, Eric Fisher and Luke Joeckel. But let's keep living in the '90s here.

The concept of a 10-year player has always been questionable when football is such a tough sport with major health risks, but roughly one in five players drafted do last that long.

NFL Draft: Career Length Splits
Draft Players 10+ Yrs Pct. 0 GP Pct. 0 XP Pct. 0 GS Pct.
1994 222 45 20.3% 30 13.5% 19 8.6% 69 31.1%
1995 249 45 18.1% 40 16.1% 21 8.4% 93 37.3%
1996 254 52 20.5% 39 15.4% 27 10.6% 83 32.7%
1997 240 47 19.6% 28 11.7% 18 7.5% 75 31.3%
1998 241 51 21.2% 37 15.4% 20 8.3% 80 33.2%
1999 253 50 19.8% 28 11.1% 13 5.1% 85 33.6%
TOT 1459 290 19.9% 202 13.8% 118 8.1% 485 33.2%

Then you have the unfortunate 20 or so players drafted each year who never even get credit for one season (0 XP) because they were cut before the regular season. I am not sure this happens as much these days, with smaller draft classes and practice squads willing to gobble up many of those players. Anyone drafted today also has a Wikipedia page with details of when they were cut and signed to practice squads, whereas we are a bit in the dark with past flame-outs from the mid-'90s.

Just fewer than 14 percent of the drafted players never played in a regular-season game. We'll soon break that down by round; as you can imagine this happens much more often in the last rounds. Roughly a third of players never start a game, which would be fine if they were kickers or punters, but only 17 of the 1,459 players were drafted for their legs. One of those 17 was the only player in this study to finish with negative career AV: kicker Steve McLaughlin, on whom the Rams foolishly wasted a third-round pick in 1995, their first year in St. Louis. McLaughlin only played in eight games and was just 8-of-16 on field goals. Well, at least they didn't trade up to get him in the second round.

Draft Results: By Round

You have probably read dozens of draft studies that reach the same obvious conclusion: the first round produces the best careers, the second and third rounds are not bad, but after the 100th pick or so, it is a real crapshoot to find any significant value. Things were no different from 1994 to 1999.

NFL Draft: By Round Averages
Round Players Years of XP Games Starts AP1 Pct. PB Pct. CarAV
1 182 9.2 120.9 100.8 39 21.4% 68 37.4% 48.9
2 190 7.7 96.8 62.8 13 6.8% 32 16.8% 28.2
3 207 6.3 73.1 38.2 12 5.8% 27 13.0% 19.1
4 204 5.5 61.1 27.6 1 0.5% 9 4.4% 13.6
5 201 4.5 47.9 20.5 4 2.0% 13 6.5% 10.4
6 223 3.8 39.7 15.3 1 0.4% 8 3.6% 7.3
7 252 3.4 32.5 12.9 2 0.8% 7 2.8% 6.4

The average first-round pick lasts nine years and starts over 100 games, which makes the "10-year starter" concept much more feasible when you are talking about a high pick. More than one-fifth of first-rounders end up as All-Pro selections, and more than a third make at least one Pro Bowl, and this was back when they didn't invite fifth alternates like today. By the time you get to the seventh round, you are lucky if that player starts a dozen games. Honestly, just making a roster is impressive. Here is the breakdown of career length from the previous section, but by round.

NFL Draft: By Round Splits
Round Players 10+ Yrs Pct. 0 GP Pct. 0 XP Pct. 0 GS Pct.
1 182 88 48.4% 0 0.0% 0 0.0% 5 2.7%
2 190 68 35.8% 4 2.1% 1 0.5% 15 7.9%
3 207 44 21.3% 12 5.8% 3 1.4% 46 22.2%
4 204 31 15.2% 16 7.8% 8 3.9% 59 28.9%
5 201 20 10.0% 34 16.9% 13 6.5% 84 41.8%
6 223 21 9.4% 58 26.0% 43 19.3% 119 53.4%
7 252 18 7.1% 78 31.0% 50 19.8% 157 62.3%

More than a quarter of sixth-round picks and nearly a third of seventh-round picks never played a regular-season game. Every first-round pick played at least one game, but five did fail to log a start in their career: Andre Johnson (1996 Redskins), Craig Powell (1995 Browns), Reggie McGrew (1999 49ers), Dimitrius Underwood (1999 Vikings) and John Avery (1998 Dolphins). All five were selected between picks 24 and 30, but Johnson may have been the worst of them all, never even playing a game with the Redskins and only logging three appearances in his career. Underwood also never played for his drafted team and was the most memorable name of the group to me, as he had a rather interesting story.

Can you recall any of the four second-round picks to never play a game? Leon Bender (1998 Raiders) is the most tragic story of this study. Just five weeks after he was drafted 31st overall, the Washington State defensive tackle passed away at the age of 22 from a seizure disorder. James Manley (1996 Vikings), Jimmy Oliver (1995 Chargers), and Shane Hannah (1995 Cowboys) were the other three without a game played.

None of the six drafts produced more than four Pro Bowlers in any of what we call today the "Day 3" rounds (Rounds 4 to 7). Some of the steals found in Rounds 4 to 7 include Terrell Davis, Zach Thomas, Jamal Anderson, Rodney Harrison, Matt Birk, Matt Hasselbeck, Derrick Mason, La'Roi Glover, Tom Nalen, Aaron Smith, Joe Horn, Al Harris and Donald Driver. Not all of them shined for the team that drafted them, but we will get to that later.

The round with the highest average AV was 1996's first round (53.0). The "deepest" later round in this study was the 1996 draft's fifth round with an average AV of 18.7. It produced six 100-plus-game starters in Zach Thomas, La'Roi Glover, Joe Horn, Fred Miller, Chris Villarrial, and Marcus Coleman. The most barren round also belonged to 1996, as its seventh round averaged a study-low 8.5 starts and 4.1 AV. That makes sense given how much talent went in the first six rounds of 1996.

The year-to-year results were fairly consistent by round, with one notable exception coming in the seventh round. Since free agency was new, the concept of compensatory picks would not come into play until the 1995 draft. So there were only 28 picks in 1994's seventh round, but then 39 to 52 picks in the 1995-1999 drafts. That may be the reason why 1994 has the best seventh-round metrics with 4.8 years of experience, 49.1 games, 18.8 starts, the only two All-Pro selections, three of the seven Pro Bowlers, and 11.1 AV.

Draft Results: By Position

Are offensive tackles the safest picks? Unfortunately, there was too much gray area in figuring out the positions, so we took a more general approach by using offensive line, defensive line, and defensive back instead of breaking things down into tackle, center, safety, defensive end, etc. There still is some gray area between defensive line and linebackers, but we generally went with what the official NFL site had, unless it was a clear error like Tom Barndt being listed as a guard when he was a defensive tackle at Pittsburgh and with the Chiefs.

NFL Draft: By Position Averages
Position Players Years of XP Games Starts AP1 Pct. PB Pct. CarAV
OL 249 6.2 68.4 50.5 13 5.2% 28 11.2% 22.9
QB 63 6.1 43.7 33.6 1 1.6% 11 17.5% 19.9
LB 210 5.5 67.7 37.3 13 6.2% 26 12.4% 19.2
DL 236 5.5 64.4 38.6 12 5.1% 23 9.7% 19.0
WR 173 5.0 57.8 31.8 9 5.2% 19 11.0% 17.5
DB 264 5.6 68.7 37.3 12 4.5% 28 10.6% 16.9
RB 161 5.1 58.5 26.7 10 6.2% 20 12.4% 15.5
K 7 6.6 77.4 0.0 0 0.0% 1 14.3% 11.7
P 10 7.2 98.2 0.0 1 10.0% 3 30.0% 11.0
TE 86 6.1 74.1 38.3 1 1.2% 5 5.8% 7.9

No position is drafted more than defensive back, with the two trenches not far behind. Punters and kickers have the longest careers, which was expected, but the offensive line is not far behind at 6.2 seasons. Wide receivers have the shortest careers at 5.0 years, which also makes sense given how dependent they are on their quarterback and situation.

However, the high-priced quarterbacks tend to have the shortest leash, averaging a study-low 43.7 games played. Remember the names of busts such as Jim Druckenmiller, Akili Smith, Cade McNown, Ryan Leaf, and Heath Shuler? None were able to start 25 games in their careers as teams were rightfully quick to dump them. Backup quarterback careers can last long with the player rarely making an appearance, but ideally you want to draft a quarterback to be your starter. Twenty-three of the 63 quarterbacks never started a game, but those were all players drafted 100th or later.

Offensive linemen average 50.5 starts, while no other position is above 40. That sounds impressive, but linemen are used to starting the game with the expectation of going the distance. Most other positions can be rotated in, but that is where the line has an advantage in these numbers. It always feels weird to talk stats at all with offensive linemen, but in terms of AV, they lead there as well as the only position to crack 20 on average. Of course, playing with a great quarterback can really help the offensive production, which is key in accumulating AV.

By these numbers, it looks really hard to draft a good tight end, though it seems like this is just a reflection of the time period more than anything. Tony Gonzalez, arguably the greatest tight end ever, was drafted in this time in 1997, but the rest of the bunch is a very unimpressive group led by Ken Dilger, Freddie Jones, Desmond Clark and Kyle Brady. Gonzalez, and later Antonio Gates, really helped push the athletic, pass-catching tight end into becoming a major part of offenses again. From 1994 to 1999, only five tight ends were drafted in the first round. That doubled to 10 in 2000 to 2005, which does not even include the prolific Gates (undrafted) and Jason Witten (third round in 2003). We have now seen another lull with two first-round tight ends since 2011, and if you played fantasy football last year, you know it felt like Rob Gronkowski or the field in most weeks.

(Ed. Note: There's also an issue where P-F-R's AV formula seems to underrate tight ends by scoring them the same way wide receivers are scored. -- Aaron Schatz)

Obviously the round matters in finding positional value, and none of the main positions do better than they do in the first round. Setting the kickers aside, this graph shows the progression of average AV for each of the eight positions by round.

Each position follows a pretty similar decay, with the offensive linemen notably spiking above their peers in the fourth and seventh rounds. Nothing is lower than a fifth-round quarterback -- something I showed in a previous study of drafted quarterbacks -- but the reason they are at zero AV here is because only Kevin Daft and Jay Barker were drafted in this period.

There are really two main types of draft analysis: what the player does, and what the drafting team gets out of the player. So far we have just covered the former, but Part II of this article, next week, will focus on the latter.

Look at that nice smooth curve for running backs. Confirms my suspicion that it's the easiest to scout position.

LBs follow reverse-Star Trek ordering (odd numbers only).

In the discussion, was "games" games played in, or games on the roster for?

I did an analysis of years as primarily a starter (started 50%+ games) across NFL history once, and the mean and median were right around 3 years. Although determining who started is... flaky pretty early heading back into history.

What was the median for kicker career? Guys like Jason Hanson kicked until their kids were old enough to take their roster spot.

4
by Scott Kacsmar :: Fri, 05/06/2016 - 3:43pm

Games played in.

There were only 7 kickers here, but the median was 7 seasons and 51 games. Steve McLaughlin and Jeff Hall were the big busts. Cole Ford and Brett Conway really didn't work out either like a kicker should. Then you had Martin Gramatica, Kris Brown and Doug Brien, who all frustrated at least one fanbase in their long careers.

Some context on those 1996 WRs. There are 89 players in NFL history with at least 500 receptions and 7,500 receiving yards. Ten of them were drafted in 1996.

Six years with pretty slim pickings for elite QBs (AP1s), other than that guy with the most AV.

They give average values, for example what is the variance? What does the distribution of 1st round QBs, RBs, etc. look like? No reason to assume average values tell the full story.

How would you visualize this? Set the lines' thickness by standard deviation?

It would be useful to see medians as well. When you have lots of low values (draft busts) and few All-worlds the average can be deceiving, e.g. if the AV was 0,5,5,20,25,75,90 the avg=31 but only 2 guys exceeded the average.

7
by Ben :: Fri, 05/06/2016 - 5:08pm

Just a side note, one of the 12 3rd round picks with zero games played was Brandon Burlsworth, the Colts 3rd rounder in 1999. He was killed in a car accident in the summer of 1999, before training camp.

by Ben :: Fri, 05/06/2016 - 5:38pm

Does the graph of the DL by round give some credence to Bill Parcels' "Planet Theory"? That is, there aren't that many freakishly athletic huge men on the planet, so when you have a chance to draft one, you should.

The drop off between the 1st and 2nd round looks like it's the largest for the DL, but then the difference between rounds 2 thru 6 is the smallest of any position.

20
by Aaron Brooks Go... :: Mon, 05/09/2016 - 8:35am

That applies mostly to DTs and partially to 3-4 DEs, but almost not at all to 4-3 DEs/3-4 OLBs. Those guys are plenty fast, but simply aren't sufficiently unusually large for planet theory to apply.

Now, it does start to reappear in a different context when you get to the really tall WRs/really fast TEs. However, the NBA grabs most of those planet theory guys.

25
by HPaddict :: Mon, 05/09/2016 - 12:37pm

I hesitate to read to much into the individual curves without knowing a bit more about the higher moments of the distribution. There is the probability of a tremendous 'influence' of randomness in the data, namely that any subset of the totality of the players will display fluctuations away from the mean.

I'd also be interested in how stable the distributions are to constructed 'uncertainties' in the size of each round.

10
by theslothook :: Fri, 05/06/2016 - 9:11pm

The round by round numbers are even more stark when one adjusts the scoring metric in a way so that its positionally independent.

Im currently away from my home computer, but will post results.

14
by tuluse :: Sat, 05/07/2016 - 12:37pm

You are going to introduce bias without separating by position. Teams draft more valuable positions higher up, IE very few TEs go in the first round compared to many QBs and pass rushers. The latter 2 will earn many more AV in their careers.

16
by theslothook :: Sat, 05/07/2016 - 1:22pm

Yes that's a good point, which is why technically, the better approach would be to post Expected Value per round instead of the actual value per round(the expected value is essentially controlling for this fact that certain positions experience a run and certain other positions get pushed down); but then I'd have to explain exactly what the formula was that led to expected value and...that would get too complicated.

12
by Scott de B. :: Sat, 05/07/2016 - 10:24am

Would like to see median games played, etc. rather than simply the average. Also would like to see Rounds 1 and 2 split into first half/second half.

13
by Tomlin_Is_Infallible :: Sat, 05/07/2016 - 11:01am

Also would be interesting to see in a few years how the more recent role of the TE and passing game affects the results.

As promised. As tuluse pointed out, it has its problems, but it does try to keep all positions on an even playing field. Also - I actually tried to correct the linebacker position, ie - separating standard linebackers from standing edge rushers - something no one else has done.

Scoring criteria - Basically, you get credit for starting 8 years, being in the league for 8 years, probowls capped at 5, all pros capped at 4. I basically grade a draft class 10 years after its introduction; so the last list added was 2006. Top score if you meet all criteria is 1000 - 1 if all you did was get drafted and get cut before the season. No fullbacks or special teamers were put in, nor were undrafted players.

Draft from 1978 to 2006

1 283
2 115
3 52
4 41
5 58
6 22
7 100

For some context: If all you did was start 8 years but garnered no probowls or all pros, you get 300.

Scoring criteria was done in a complex way, but basically what fit the data best.

19
by whateverdude :: Sun, 05/08/2016 - 1:08am

I'm assuming 7 is "7th round and later", to account for when the draft was longer?

34
by theslothook :: Mon, 05/09/2016 - 11:15pm

It was stopped at pick 262 - the longest draft pick in the modern era. Whoops, that 7th round was meant to be 16. Damn pivot table at the bottom.

21
by RickD :: Mon, 05/09/2016 - 11:35am

Was amused at the bump in Round 6 at QB - but apparently this data set doesn't include the 2000 draft, which is when Brady was drafted?

No, but it does include the guy who if not for Brady would be known as the great 6th round steal at QB of our generation... Matt Hasselbeck.

Two time probowler Mark Bulger was also a 6th round pick.

Edit: the ends points do cause weird things though. Mark Brunell was a 5th round pick in 1993.

Figured I was missing someone else. Immediately though of Hasselbeck, didn't realize Bulger was a 6th also - I assumed he was undrafted for some reason.

It is weird how the 6th round has produced three different pro-bowl caliber starting QBs (and in one case of course one of the best ever), while the 5th round has produced pretty much nothing at QB since 1994.

If you go back to 1993, you also get Pro Bowl 8th-rounders Elvis Grbac and Trent Green.

Brunell was the best 5th round QB since the merger.

Brady is the only 100+ AV QB picked after the 3rd round. (Although Gannon finished with 99)

The only active guys with even a chance to get to 100 are Fitzpatrick (3 years at current production), Cousins (7), and Taylor (7).

Hasselbeck is still active!

He only needs Luck to be hurt for three more seasons.

He also needs to not be on the far side of 40.

Career AV as given by PFR searches isn't strictly additive (worse years are weighted less heavily), so Fitzpatrick would need 5 years of last year's production, Taylor 9, and Cousins 10 to reach 100 career AV. (Matt Cassel only needs 5 years at 2008-level production to reach 100. All he needs is the 2008 Patriots surrounding cast.)

CarAV - career approximate value. See the entry on AV. The Career AV is computed by summing 100% of the player's best-season AV, 95% of his second-best-season AV, 90% of his third best, and so on. The idea is that the Career AV rating should weight peak seasons slightly more than "compiler"-type seasons.

That doesnt count for this graph because bulger was also in the 2000 draft.

Why are DB'd drafted most frequently, were teams commonly using the nickel back then so there were essentially 5 starters? You would think with 5 starters OL would be the most drafted, but I guess the longevity pushes the need down.

Consider also that backup DBs often play on return teams.

Does the rapid fall-off from the first round imply that you should trade out of the later rounds for more first round picks? Or would the cost be so high that you would have a roster made up of 10% studs and 90% SFA's

What a fantastic analysis--thank you for this!

This kind of analysis could prove even more illuminating once snap count data can be folded in, although I can't be sure I'll still be alive when it becomes possible.

Everyone tends to average and best fit curve. I'd rather see a distribution by position by round. If I'm an NFL team, I care much less about the average cAV and more about the probability of a hit over a particular threshold. (And maybe in the first round, the probability of not busting below a certain threshold). There's enough raw data to use and make my own, I guess.

A player has to surpass at least the threshold of the average UDFA to add value, or if we're team specific, the player has to surpass the cAV of the worst projected 53man player to add utility/value. Anything less and the team should trade away the pick for future picks
