538: Is Denver’s Pass Defense Even Better? 

Today at 538: yes, really, Denver’s pass defense is even better this year.

Football studies have generally shown that offenses are more consistent from year to year than defenses, and regression to the mean is always a key part of any analysis for a historically great unit. As a result, we wouldn’t expect Denver’s 2016 pass defense to be anywhere near as good as the 2015 one. And that’s exactly what you see with most of the other teams on the list above.

The other pass defenses on the top 20 list above were, on average, 1.53 net yards per attempt better than average against the pass in their dominant season; however, in their first eight games of the following season, they were just 0.52 NY/A better than average. That’s a sign of how difficult is it for dominant defenses to sustain that level of excellence over a long period. Defensive backs and pass rushers are two of football’s most health-dependent roles, and even one player losing a step or leaving in free agency can sink a unit. But so far this season, the Broncos have been even better that last season, jumping from 1.30 NY/A better than league average to 1.73.
