2011 DEFENSIVE LINES

Regular season totals, playoffs not included

Revised as of 1/2/2012

Teams are ranked according to Adjusted Line Yards. Based on regressionanalysis, the Adjusted Line Yards formula takes all running back carries andassigns responsibility to the offensive line based on the following percentages:

  • Losses: 120% value
  • 0-4 Yards: 100% value
  • 5-10 Yards: 50% value
  • 11+ Yards: 0% value

These numbers are then adjusted based on down, distance, situation,opponent, and the difference in rushing average between shotguncompared to standard formations. Finally, we normalize the numbers sothat the league average for Adjusted Line Yards per carry is the sameas the league average for RB yards per carry. Defensiveline stats (more accurately, defensive front seven stats) represent theperformance of offensive lines against each defense, adjusted for the quality ofoffensive opponents. These stats are explained further here.

The following stats are not adjusted for opponent:

  • RB Yards: Yards per carry by running backs against this defense,according to standard NFL numbers.
  • Power Success: Percentage of runs on third or fourth down, two yards or less to go, thatachieved a first down or touchdown. Alsoincludes runs on first-and-goal or second-and-goal from the two-yard line orcloser. This is the onlystatistic on this page that includes quarterbacks. Teams are ranked fromlowest power success percentage allowed (#1) to highest power successpercentage allowed (#32).
  • Stuffed: Percentage ofruns where the running back is tackled at or behind the line ofscrimmage.Rankedfrom most stuffs (#1) to fewest stuffs (#32).
  • Second Level Yards: Yards earned by opposing running backs against this team between 5-10 yards past the line of scrimmage, divided by total running back carries.
  • Open Field Yards: Yards earned by opposing running backs against this team more than 10 yards past the line of scrimmage, divided by total running back carries.

NFL averages for each stat given in red.

Why are these rankings different from the teamdefense DVOA ratings for rushing? Among other reasons, they don'tinclude quarterbacks or fumbles, long runs are truncated, and a different set ofadjustments is used, attempting to isolate line play rather than total teamdefense.

A team with a high ranking in Adjusted Line Yards but a low ranking in 10+Yards has a strong defensive line but its linebackers and secondary havedifficulty in pursuit and tackling. A team with a low ranking in Adjusted LineYards but a high ranking in 10+ Yards generally allows runners to get past thedefensive line but the linebackers and secondary are good at pursuit andtackling. A low ranking in Adjusted Line Yards with a high ranking in 10+ Yardsis often an indicator of a 3-4 defensive scheme, though there are exceptions.

Stats in blue represent pass rush. Teams are ranked according toAdjusted Sack Rate, which gives sacks (plus intentional grounding penalties) perpass attempt adjusted for down, distance, and opponent. Passrush stats areexplained further here.Our sack totals may differ slightly from official NFL totals depending on theleague's retroactive statistical adjustments.

This second table lists each team's Adjusted Line Yards in each direction listedin official NFL play-by-play, along with rank among the 32 teams. Only fivedirections are listed because research so far shows no statistically significantdifference between how well a team performs on runs listed middle, left guard,and right guard. These runs are from the perspective of the OFFENSE, so a runlisted as LEFT TACKLE is actually at the RIGHT defensive end.
