The coach who ended a decades-long drought, only to face a sudden exit
In short: Sean McDermott transformed the Buffalo Bills from a struggling franchise into a perennial playoff contender. After ending the longest active postseason drought in North American sports, his nine-season tenure concluded with a surprising firing, leaving behind a complex legacy of defensive brilliance and controversial leadership.
Taking the helm of the Buffalo Bills in 2017, McDermott inherited a franchise that had struggled through much of the 2000s and 2010s. His impact was immediate; in his first season, he led the team to its first playoff appearance since 1999, effectively ending the longest active postseason drought across the four major North American professional sports. His tenure was marked by sustained success, including five consecutive division titles and eight total playoff appearances, including a streak of seven years in a row.
McDermott’s defensive expertise was forged in Philadelphia, where he served under Andy Reid from 2001 to 2010, and in Carolina, where he was the defensive coordinator for a team that reached Super Bowl 50 in 2015. While his defensive units were often elite—notably leading the Panthers to top-ten finishes from 2012 to 2015—his offensive decision-making and play-calling occasionally drew intense scrutiny. This was most evident during a 2020 AFC Championship loss to the Kansas City Chiefs, where critics questioned his choice to attempt field goals rather than touchdowns on critical fourth-and-goal plays.
Despite the highs, McDermott's leadership was not without controversy. In 2019, reports surfaced regarding a team meeting where he used a highly criticized analogy, comparing the team's need for coordination to the tactics used by the September 11 terrorists. McDermott later apologized for the remark. His era ended on January 19, 2026, when the Bills fired him following a 2025 season that saw a divisional loss and an overtime defeat to the Denver Broncos. While he achieved significant milestones, including becoming second on the Bills' all-time wins list, he was unable to secure a Super Bowl victory.
