This page lists DVOA (Defense-adjusted Value Over Average) for total defense as well as rushing and passing defense separated. The DVOA system is explained here. DVOA stats are adjusted to an average percentage of fumbles recovered by the offense. Quarterback scrambles are counted as passing plays rather than rushing plays. Defenses are adjusted for playing indoors.
Remember, since positive numbers represent more scoring, defense is better when it is NEGATIVE.
Regular season only.
Note for 1987: strikebreaker games (Weeks 4-6) are not included.
For 2022 only: DAVE, or DVOA Adjusted for Variation Early, is a formula which combines our preseason forecast with current weighted DVOA to get a more accurate projection of how a team will play the rest of the season. DAVE is currently 7% preseason forecast and 93% actual performance for teams with 12 games and 16%/84% for teams with 11 games.
UNADJUSTED VOA numbers do not include adjustments for opponent and only reward defenses for lost fumbles. The adjustment for playing indoors is still present.
SCHEDULE lists average offensive DVOA of opponents played this season, ranked from hardest schedule (#1, most positive) to easiest schedule (#32, most negative). It is not adjusted for which games are home or road.
VARIANCE measures the statistical variance of the team's weekly DVOA performance. Teams are ranked from most consistent (#1, lowest variance) to least consistent (#32, highest variance).
