Mathis takes down Manning

Mathis takes down Manning.

Good stat courtesy of Bill Barnwell this week: Robert Mathis has 11.5 sacks, while the rest of his Indianapolis teammates have just 10.5 sacks. Jerrell Freeman is second on the team with 3.5 sacks, Cory Redding has a pair of sacks, and no other Colt has more than one sack. That’s obviously very impressive: no other defensive player in 2013 has even 40% of his team’s sacks, with only LaMarr Woodley (5 sacks), Mario Williams (11), and Robert Quinn (10) having more than one-third of their team’s sacks.

Since the sack became an official statistic in 1982, the record for percentage of team sacks by an individual player was set by right outside linebacker Tim Harris on the 1989 Packers. Green Bay ran a 3-4 defense under Hank Bullough, and Harris had 19.5 of the team’s 34 sacks.  That means 57.4% of all sacks by Packers players that year came from Harris; no other Green Bay player had more than three sacks.

Aldon Smith had 19.5 sacks, too, playing on the 2012 49ers. Last year, San Francisco recorded 38 team sacks, meaning Smith — playing that same ROLB position in the 3-4 defense — had 51.3% of his team’s sacks.  Two other players recorded exactly half of their team’s sacks.  In 1984, when Mark Gastineau (playing at left defensive end in New York’s 4-3 defense) set the sack record, he recorded 22 of the Jets 44 total sacks. Fifteen years later, Football Perspective All Underrated star Simeon Rice (who lined up at right defensive end) had 16.5 of the Cardinals 33 sacks.

Mathis was a star 4-3 defensive end, but he’s already matched his single-season career high in sacks. He’s having perhaps his best season playing as rush linebacker in the system devised by Greg Manusky and Chuck Pagano. And his numbers look even better as a percentage of team sacks. Below are the top 50 leaders from 1982 to 2012 in percentage of team sacks, which is a cut-off deep enough to bring in another Robert Mathis season:

J.J. Swatt.

Houston’s J.J. Watt sacked Andrew Luck three times on Sunday, bringing his season sack total to 19.5. Entering 2012, Bruce Smith was the single-season record holder for sacks by a defensive lineman in a 3-4 scheme with 19 in 1990. The sack has only been an official statistic since 1982, but since the 3-4 only entered the NFL in the mid-’70s, we can be pretty sure that Watt is now the all-time record holder.

The tables below show the single-season leaders by various defensive players in 3-4 and 4-3 schemes from 1982 to 2011.

Let’s start with a look at the most sacks by a 3-4 defensive end:

As you can imagine, 3-4 defensive linemen don’t rack up many sacks. Bill Pickel, a nose tackle for the Raiders in the ’80s, recorded 12.5 sacks in both ’84 and ’85, making him the only 3-4 tackle to record more than 12 sacks in a season. Karl Mecklenburg, with 13 sacks for the Broncos in ’85, remains the only inside linebacker in a 3-4 with more than a dozen sacks.

Of course, 3-4 outside linebackers get all the glory in that scheme. San Francisco’s Aldon Smith has 19.5 sacks so far in 2012 with two games remaining, but here were the leaders prior to 2012:

4-3 outside linebackers rarely rack up huge sack numbers. In fact, Denver’s Von Miller, who has 16 sacks this year, is already the record holder in the official sack era. Derrick Thomas (14.5 sacks in 1992, 13 in 1996) in Kansas City, Washington’s Ken Harvey (13.5 in ’94) and Cleveland’s Jamir Miller (13 in ’01) are the only other 4-3 outside linebackers with more than twelve sacks in a season since 1982. (Of course, Thomas also had a 20-sack season a 3-4 outside linebacker.) Charlie Clemons, with 13.5 sacks in 2001, is the record holder among 4-3 middle linebackers.

Thirty years ago, the NFL began officially recording defensive player sacks. Prior to 1982, all teams kept their own individual sack data, but those records (with few exceptions) have never been verified. As a result, it’s an unfortunate reality that for much of NFL history, we simply do not have reliable sack data for individual defensive players.

Three times, Deacon Jones produced 20+ unofficial sacks in the 1960s.1 In 1967, Raiders defensive end Ben Davidson had 17 sacks2 in the AFL. Jack Youngblood and Jim Katcavage both led the league in sacks on two different occasions in the pre-1982 era.3 Cincinnati Bengal Coy Bacon has been credited with 21.5 unofficial sacks during in 1976. The first team to record 60 sacks in a season was the ’57 Bears, and we can be sure that Doug Atkins recorded more than his fair share of that number. For players like Gino Marchetti, Norm Willey, and Len Ford, even unofficial records weren’t kept during their time, leaving us unsure as to who is the true sack king.

It’s important to remember that just because we don’t have official sack data before 1982 doesn’t mean there were great sack artists before then. But that’s a topic for another today. So while we can’t precisely measure how the forefathers of the game played, we do have official data for the last 30 years. So who has been the best pass rusher of the last three decades?

Brett, are you SURE you're okay?

Using total sacks isn’t a fair method to current players, or to those players who chose to retire instead of sticking around to compile six-sack seasons. So if we want to measure sack dominance, we can’t simply look at total sacks any more than we can grade running backs by looking at career rushing yards. One method I like that I’ve used before is sacks over one-half sack per game. This makes 8 sacks in a 16-game season the bar; a player only gets credit for their production over that level. This means that 12 sacks in a 16-game season brings a value of +4.00, while 16 sacks is twice as valuable at +8.00.There’s no great reason to choose 8 over 6 or 10 or any other number. I chose 8 because it feels right, but I don’t claim that it’s based on anything other than my personal, subjective preference.
