The Buffalo Bills answered one big question when they hired Sean McDermott as their new head coach, starting in the 2017 season. With that hire, a ton of the questions on the defensive side of the ball were determined.
It is likely that the team will switch to a 4-3 scheme rather than a 3-4 scheme like Rex Ryan ran in his time with the Bills — one that has been highly criticized for not working given the personnel he was working with.
Still, despite those defensive questions being answered, a lot of offensive questions remain.
