The Buffalo Bills have interviewed Mike Caldwell for defensive coordinator, per a source shared through Mike Garafolo of NFL Network. Caldwell was previously the defensive coordinator for the Jacksonville Jaguars during the 2022 and 2023 NFL seasons.
Caldwell played linebacker in the NFL for 11 seasons and six teams — including the Philadelphia Eagles where Caldwell and current Bills head coach Sean McDermott first met. Following Caldwell’s NFL career, he entered the coaching ranks in 2008 as a defensive quality control coach with the Eagles, and was eventually promoted to assistant linebackers coach all while McDermott was still with Philadelphia.
