Should what you say become the norm I can see that happening in the league, but McDermott is pretty wed to “his zone style” come hell or high water so to speak, an “adjustment” like that on Sean’s part would be a bit of a surprise imo, just look at the playoffs, he gets caught with his pants down every post season for the lack of effective adjustments, I say this as a gentle critique, in which I think for the most part Sean is pretty obviously an above average HC, and by win loss record, the best the Bills have had in the modern era.
