‘I’m still interested to hear whether McDermott will call plays, as some coaches do, even with coordinators. You see that more often with offensive coaches, such as Kyle Shanahan or Sean McVay. The defense had some struggles, particularly in the middle of the season, but it’s hard to quibble with the play-calling job he did on the whole of the season with as injury depleted as the Bills became. Yes, the season came to an end in part because of the failure to slow down Kansas City in the second round, but as we saw in the first half of the AFC Championship, even the best defense in the league had trouble with Patrick Mahomes and Travis Kelce.’
