Brady’s elevation suggests the Bills will try to preserve most of their offensive staff, leveraging his specialty as an offensive-minded coach. However, the defense likely faces a broader reconfiguration, requiring a fresh strategic direction to complement the new head coach.
Hours after Brady’s hiring, ESPN’s Adam Schefter reported Buffalo could target Jim Leonhard as defensive coordinator. Leonhard, who played defensive back for the Bills from 2005 to 2008, has built a coaching résumé at Wisconsin and Illinois before joining the Broncos in 2024, where he helped shape one of the league’s top defenses this season. With the Broncos out of the playoffs, Buffalo could pursue him at any time.
The Bills will need to adjust to a new defensive philosophy with McDermott no longer in the leadership role. Shifting away from a long-standing defensive identity may prove challenging for players who have trained in the same system for years, even as they pursue a high-powered offense.
Introducing two relatively young, first-time leaders—Brady as head coach and a potential Leonhard as defensive coordinator—could bring growth pains in the short term. Buffalo remains a top contender in the AFC with Josh Allen, who turns 30 this year and is still entering his prime years, but a sharp transition could affect the team’s immediate Super Bowl pursuit.
It will be interesting to see how Brady performs in his first season as head coach and how Buffalo balances continuity with change as it aims to compete for another deep playoff run.
