Over the course of the history of the NFL, we have seen head coaches who have been great and horrible. Some were with a team for a long time, and some not so much. The Buffalo Bills have had some great coaches, and of course some bad coaches over the course of their franchise history.
Sean McDermott has the chance to become the best head coach in Bills history if he can help deliver the franchise’s first Super Bowl. He will pass Marv Levy as the best in team history, but McDermott is facing an uphill challenge that the Bills have been stuck in the last five years: getting to the Super Bowl.
