With rumors swirling that Buffalo Bills defensive coordinator Leslie Frazier has been contacted about an interview for the vacant Indianapolis Colts head coaching job, there is a possibility that the Bills will be in the market for a new defensive coordinator. Given the timing of such a move, it puts the Bills in a difficult spot regarding hiring a replacement for Frazier with so many coaches already under contract elsewhere.
Most likely, the team would make a move to promote someone from within the organization. With that in mind, the most likely candidate to replace Frazier should he leave for the Colts would be current linebackers coach Bob Babich.
