Sure, but McDermott would have had this team competing hard each week even with Kyle Allen. I wouldn't be surprised to see this as a fringe playoff team without Allen. McDermott is basically Mike Tomlin, they will both not accept a losing season. Bills won 6 games in 2018, starting 4 different QBs (Peterman, Allen, Anderson and Bakley) and one of the worst rosters in football.
With a better roster now, even without Allen, I could see McDermott winning 9 ugly ugly games
