Sean McDermott reached another impressive milestone in his coaching career after Buffalo's big win over Kansas City. McDermott has become the second winningest head coach in Bills history.
The head coach now has 69 total wins since becoming Buffalo's coach in 2017. McDermott passed Lou Saban who has 68 wins and is behind Marv Levy who has 112 wins. He also has the highest win percentage in franchise history with .627 (69-41).
Amid the 69 wins, McDermott has led his team to three straight AFC East titles (2020-2022) for the first time since 1988-1991.
Buffalo's HC also helped instill a winning culture that led the team to five playoff appearances in McDermott's first six seasons. His first postseason appearance in 2017 broke Buffalo's 17-year playoff drought. McDermott also became the third coach in Bills history to earn a playoff spot in his first season.
The HC has produced four consecutive seasons (2019-2022) with at least 10 wins and is three wins away from five straight. Buffalo and Kansas City are the only two teams to win at least 10 games and earn a playoff berth in each of those seasons.
Since 2017, McDermott has coached defenses that have ranked among some of the best in the league. Buffalo's defense ranks first in the NFL takeaways (179), total yards allowed per game (315.4), passing yards allowed per game (202.3), passer rating allowed (80.2) and passing touchdowns allowed (123). They rank second in total yards allowed per game (315.4) and interceptions (109). They also rank third in points allowed per game (19.9) and third down conversion rate allowed (36.6%) since 2017.
In 2021, the defense ranked first in fewest points allowed per game (17) for the first time in Bills history. The group also finished the season ranking first in fewest yards allowed per game (272.8) and fewest passing yards allowed per game (163).
