Tampa Bay is still No. Plus, a look at Seattle and other teams with a strong imbalance between offense and defense. And on the other side of the ledger, the Jets are far behind the rest of the league.
It's a weird week with some scrambled DVOA ratings. There is also an additional adjustment dropping the value of field goals in Florida because the warm temperatures allow the ball to carry better and raising the value of punts in San Francisco because of those infamous winds.
Baselines have also been adjusted each year to make up for the gradual improvement of kickers over the last two decades. As a final step, we then normalize special teams DVOA to reflect the league environment in a given year.
Obviously, there are no defenders standing on the yard line, ready to block a kickoff after the whistle blows.
The special teams formula now includes adjustments to give teams extra credit for field position on kick returns if kickers are deliberately trying to avoid a return.
The other two items that special teams have little control over are field goals against your team, and punt distance against your team.
Research shows no indication that teams can influence the accuracy or strength of field-goal kickers and punters, except for blocks.
As mentioned above, although blocked field goals and punts are definitely skillful plays, they are so rare that they have no correlation to how well teams have played in the past or will play in the future, thus they are included here as if they were any other missed field goal or botched punt, giving the defense no additional credit for their efforts.
Special teams ratings also do not include two-point conversions or onside kick attempts, both of which, like blocks, are so infrequent as to be statistically insignificant in judging future performance.
Actually, these are only measures of running plays, and of course the defensive numbers don't measure just the defensive line, but the whole front seven against the run.
One of the most difficult goals of statistical analysis in football is somehow isolating how much responsibility for a play lies with each of the 22 men on the field.
Nowhere is this as obvious as the running game, where one player runs while up to nine other players -- including wideouts, tight ends, and fullback -- block in different directions.
None of the statistics we use for measuring rushing -- yards, touchdowns, yards per carry -- differentiate between the contribution of the running back and the contribution of the offensive line.
We have enough data amassed that we can try to separate the effect that the running back has on a particular play from the effect of the offensive line and other offensive blockers and the effect of the defense.
A team might have two running backs in its stable: RB A, who averages 3. Who is the better back? Imagine that RB A doesn't just average 3. The difference in variability between the runners can be exploited to not only determine the difference between the runners, but the effect the offensive line has on every running play.
We know that at some point in every long running play, the running back has gotten past all of his offensive line blocks.
From here on, the rest of the play is dependent on the runner's own speed and elusiveness, combined with the speed and tackling ability of the defensive players.
If Frank Gore breaks through the line for 50 yards, avoiding tacklers all the way to the goal line, his offensive line has done a great job -- but they aren't responsible for most of that run.
How much are they responsible for? For each running back carry, we calculated the probability that the back involved would run for the specific yardage on that play, based on that back's average yardage per carry and the variability of their yardage on every play.
We also calculated the probability that the offense would get the yardage based on the team's rushing average and variability without the back involved in the play, and the probability that the defense would give up the specific amount of yardage based on its average rushing yards allowed per carry and variability.
Thus, the creation of Adjusted Line Yards. Adjusted Line Yards take every carry by a running back and apply those percentages.
Those numbers are then adjusted based on down, distance, situation, opponent and whether or not a team is in the shotgun.
Because defenses are generally playing pass when the quarterback is in shotgun, the average running back carry from shotgun last year gained 5.
The adjusted numbers are then 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 , 4.
Further research showed no statistically significant difference between how well a team performed on runs listed middle, left guard, and right guard, so we also list runs separated into five different directions.
We don't know when a guard is pulling and when a guard is blocking straight ahead. We know that some runners are just inherently better going up the middle, and some are better going side to side, and we can't measure how much that impacts these numbers.
We have no way of knowing the blocking contribution made by fullbacks, tight ends, or wide receivers. The stats section of our website also features drive stats compiled by Jim Armstrong.
These stats are computed from NFL Drive Charts and are not adjusted for strength of schedule or situation. Take-a-knee drives at the end of halves are discarded.
Drive stats are generally self-explanatory, giving each team's total number of drives as well as average yards per drive, points per drive, touchdowns per drive, punts per drive, and turnovers per drive, interceptions per drive, and fumbles lost per drive.
Drive stats are given for offense and defense, with NET representing simply offense minus defense. Our data may differ slightly from official NFL numbers due to discrepancies in different play-by-play reports.
In addition, we've adjusted clock plays, with kneels no longer counting as rush attempts and spikes no longer counting as pass attempts. Prior to , we also counted aborted snaps as passing plays, not rushing plays, unless the play-by-play specifies that the play was an aborted handoff.
Beginning in , we are counting aborted snaps as rushing plays in the same way as the official NFL stats.
Football Outsiders Information. Methods To Our Madness. The beauty of this statistic is that it can be used to compare teams as a whole or in any situation you can think of as well as players.
Third downs in the fourth quarter? Likewise, the same play is scored for the Bengals defense, comparing the result to how other defenses fare in that situation, then adjusting for the quality of the Steelers offense.
It actually holds value and can really shows how efficient a quarterback really is rather than spouting an impressive-sounding box score.
DVOA can also be used to grade teams as a whole on both sides of the ball. The Packers ran 76 plays to the Vikings 49 and Minnesota, as mentioned above, scored 24 points in the fourth quarter.
That undoubtedly had an effect on the DVOA scores. Finally and perhaps most simply, the Vikings averaged more yards per play than the Packers did; Green Bay, like Minnesota, actually had its best yards per play in the fourth.
Since DVOA is generated on a play-by-play basis, it now makes sense to how this happened, as weird as it is. This should eventually get straightened out as the season wears on, but it is worth pointing out.
All this considered, does that invalidate DVOA as a statistic? Preregistration only. Welcome to Orienteering Orienteering is an outdoor navigation sport.

Did that just bring your brain to a screeching halt?Author: Kris Burke. What Is DVOA? To put it simply, DVOA (a metric created by Football Outsiders) tells us a little bit more about a team’s strengths and weaknesses than “yards per” can account for. If a team ranked 8th in yards allowed per carry, for example, but were 16th in DVOA, it would essentially mean that they weren’t as good as that first statistic made them appear.

By definition, a median level of performance is better than that provided by half of the league and the ability to maintain that level of performance while carrying a heavy work load is very valuable indeed.
