Under McDermott the Bills have lost (DQ is partially back) the key player(s) at each level of the D in 2023. Still, the Bills are playing excellent D and I would argue, without great complimentary football as the O has been very inconsistent this year. I know many here are down on McDermott but he does deserve credit as the D has been an absolutely pleasant surprise this year.
The other very honorable mention here is that Rasul Douglas may well be the best pickup trade ever by the Bills. Credit to him and to the Bills coaching staff. McDermott is a secondary whisperer. Hell even Austin looked good for the Cheats*.
Let’s hope the offense finds a gear in Miami. The D has found theirs.
