Ed Donatell and Vic Fangio worked magic with the 2021 Denver Broncos defense.
The most important stat is points allowed and the Broncos finished third in points allowed (322). The team allowed 36 touchdowns but only 31 were against the defense, the offense allowed three and the special teams allowed two. In terms of defensive points allowed, the Broncos defense was second only to the Patriots. The Patriots allowed 303 points and five of those touchdowns were not against the defense (four on the offense and one on special teams). Compare that to the Bills who allowed 289 points with only one score not directly allowed by the defense (blocked punt).
