Jim Schwartz tells Bills he won't return in 2015

Bills defensive coordinator Jim Schwartz has informed coach Rex Ryan he will not return for the 2015 season due to "differing defensive philosophies," a league source told Adam Caplan of ESPN. The Bills announced his contract was terminated Tuesday. Buffalo has moved quickly and are reportedly set to hire ex-Jets defensive coordinator Dennis Thurman to the same position.

Schwartz is regarded as a strong defensive coordinator, and does have experience as a coach. From 2009 to 2013, Schwartz complied a 29-51 record in five seasons with the Lions. He was already receiving strong interest from other teams looking to fill the role of defensive coordinator before the announcement of his departure.
