In a vacuum, Sean McDermott ranks right up there with Lou Saban and Marv Levy as the most successful head coaches in the history of the Buffalo Bills. Saban won two straight AFL titles with the team in 1964 and 1965, and Levy went to four straight Super Bowls between 1990 and 1993, famously losing all four. McDermott’s .624 regular-season win percentage places him in the Pantheon of head coaches in the annals of professional football. His .444 postseason record is another matter, and the Bills’ 6-6 record in the 2023 season — armed as it’s been with issues on all sides of the ball — has some people wondering if the Bills have wasted perhaps the best and widest window the franchise has ever had to take home its first Lombardi Trophy.
