Many here would say that the Bills defense was not as good as the statistics indicated. Probably most would agree that the Bills 2021 D did not generate enough sacks and was too porous against the run.
You might argue that the defense cost the Bills 3 of their six losses (TN, IND & Cheats*) and there are those who will say the Bills D lost the game in KC. In many ways this metric is meaningless as it takes all three phases to win games. The phases also play off one another.
However, for purposes of discussion in this thread - does the Bills D get better in 2022? If so, Does the D truly become elite in that it wins you games not just plays statistically well?
