The Buffalo Bills are expected to hire Jim Leonhard as their new defensive coordinator, according to reports from ESPN’s Adam Schefter. The move would bring Leonhard back to Buffalo, where he previously played as a safety during his NFL career.
Leonhard, 43, has built a solid coaching reputation over the past several years, particularly for his work with the University of Wisconsin football program, where he served as defensive coordinator from 2017 to 2022. During his time with the Badgers, Leonhard’s defenses were consistently among the top-ranked units in the country in multiple statistical categories, including total defense, scoring defense, and third-down efficiency.
After stepping down from his role at Wisconsin, Leonhard took time away from the game but remained a sought-after name in coaching circles for both collegiate and professional teams. His return to the NFL, assuming the hire is finalized, would mark his first professional coaching role and a reunion with the Bills organization where he began his playing career in 2005.
The Bills’ decision to bring in Leonhard likely reflects a broader effort to reshape their defense following a season marked by injuries and uneven performances. Buffalo finished the regular season with a strong record but showed vulnerabilities on the defensive side of the ball, especially in the latter stages of the season and playoffs. The team had previously relied on longtime defensive coordinator Leslie Frazier, who stepped away from coaching prior to the 2023 season.
Leonhard’s schemes at Wisconsin were known for their adaptability, discipline, and ability to create turnovers—traits the Bills could benefit from as they continue to contend in the AFC. His familiarity with the organization and leadership potential may also play key roles in his transition to the NFL coaching ranks.
As of now, the Bills have not made an official announcement regarding the hire.
