2012 OFFENSIVE LINES
By
Aaron Schatz
Created
08/29/2012 - 11:38pm Offensive Line Regular season totals, through Week 5
Revised as of 10/9/2012
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. These stats are explained further
here [1].
The following stats are not adjusted for opponent:
- RB Yards: Yards per carry by that team's running backs, according to standard NFL numbers.
- Power Success: Percentage of runs on third or fourth down, two yards or less to go, that achieved a first down or touchdown. Also includes runs on first-and-goal or second-and-goal from the two-yard line or closer. This is the only statistic on this page that includes quarterbacks.
- Stuffed: Percentage of runs where the running back is tackled at or behind the line of scrimmage. Since being stuffed is bad, teams are ranked from stuffed least often (#1) to most often (#32).
- Second Level Yards: Yards which this team's running backs earn between 5-10 yards past the line of scrimmage, divided by total running back carries.
- Open Field Yards: Yards which this team's running backs earn 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
team offense [2] 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 teamoffense.
A team with a high ranking in Adjusted Line Yards but a low ranking in Open FieldYards is heavily dependent on its offensive line to make the running game work.A team with a low ranking in Adjusted Line Yards but a high ranking in Open Field Yardsis heavily dependent on its running back breaking long runs to make the runninggame work.
However, it is important to understand that these ratings only
somewhatseparate the offensive line from the running backs. A team with a verygood running back will appear higher no matter how bad their line, and a teamwith a great line with appear lower if the running back is terrible.
Stats in blue represent passblocking. Teams are ranked according to Adjusted Sack Rate, which gives sacks (plus intentional grounding penalties) perpass attempt adjusted for down, distance, and opponent. Pass blocking stats areexplained further
here [3].Our sack totals may differ slightly from official NFL totals depending on theleague's retroactive statistical adjustments.
