These numbers are then adjusted based on down, distance, situation, and opponent, and normalized so that the league average for Adjusted Line Yards per carry is the same as the league average for RB yards per carry (in 2005, 4.08). These stats are explained further The following stats are not adjusted for opponent RB YardsYards per carry by that team's running backs, according to standard NFL numbers.10+ Yards: Percentage of a team's rushing yards more than 10 yards past the line of scrimmage. Represents yardage not reflected in Adjusted Line Yards stat.
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 that result in (on first down) zero or negative gain or (on second through fourth down) less than one-fourth the yards needed for another first down. Since being stuffed is bad, teams are ranked from stuffed least often (#1) to most often (#32).NFL averages for each stat given in red.Why are these rankings different from DVOA ratings for rushing? Among other reasons, they don't include quarterbacks or fumbles, long runs are truncated, and a different set of adjustments is used, attempting to isolate line play rather than total team offense.A team with a high ranking in Adjusted Line Yards but a low ranking in 10+ Yards 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 10+ Yards is heavily dependent on its running back breaking long runs to make the running game work.However, it is important to understand that these ratings only somewhat separate the offensive line from the running backs. A team with a very good running back will appear higher no matter how bad their line, and a team with a great line with appear lower if the running back is terrible.
Stats in blue represent pass blocking. Teams are ranked according to adjusted sack rate, which gives sacks per pass attempt adjusted for opponent, down, and distance. Pass blocking stats are explained further . Our sack totals may differ slightly from official NFL totals depending on the league's retroactive statistical adjustments.
