The Wisconsin Badgers are becoming a direct pipeline to the Buffalo Bills coaching staff now that Jim Leonhard is taking over as defensive coordinator.
As he fills out his defensive staff with his own assistants, he is dipping into his network of former Badgers and bringing them back together in Buffalo.
The latest addition to his staff also happens to hurt the Minnesota Golden Gophers in the process. Leonhard is bringing in Bobby April III to be the Bills new outside linebackers coach.
