McDermott leaves with a 98-50 record in nine seasons, eight playoff appearances, and five straight AFC East titles from 2020 through 2024, marking a sustained period of success in Buffalo.
In his farewell message, McDermott thanked the Pegula family, the Bills organization, and the fans, calling coaching the team a gift and expressing gratitude for the opportunity to lead in Buffalo.
On the replacement front, reports indicate the Bills are expected to interview Broncos quarterbacks coach and passing game coordinator Davis Webb for the vacancy. Webb is also reported to be in the mix for the Raiders, per Ian Rapoport, and NBC Sports.
Webb, a former Bills quarterback, is largely credited with helping Bo Nix develop into the passer he is today, a factor amid growing interest in his candidacy. The Bills’ coaching search remains active with no formal hire announced.
