‘Through five weeks of the NFL season, no coordinator has his offense or defense playing better football than Frazier’s no. 1-ranked Bills defense. Buffalo ranks 1st in points allowed per game (12.1), yards per game (251.8), and total turnovers forced (15). Football Outsiders created the DVOA stat metric to rank teams based on how each play a team runs compares to the NFL league average. The statistic takes into account quality of opponent, game situation, and spits out a percentage. The Bills have a -42.9% DVOA, which ranks 2nd-best of any defense since 1983.’
