Buffalo Bills head coach Sean McDermott now holds the franchise’s win percentage record among the team’s all-time list of head coaches, doing so in dramatic fashion as he faced off against his former William & Mary teammate and friend, head coach Mike Tomlin.
With the Bills’ Week 5 victory over the Pittsburgh Steelers Sunday afternoon, McDermott’s win percentage record with Buffalo increased to .616 (53-33). The win allowed McDermott to move into first place past legendary Hall of Fame head coach Marv Levy, who holds a .615 win percentage (182-112). Levy led the Bills from 1987-1997—during the team’s incredible and still unmatched feat of playing in four consecutive Super Bowls—and then returned as the team’s general manager from 2006-2007.
