According to Alex Marvez of FOX Sports, the Cleveland Browns have an interest in Chan Gailey filling their vacant offensive coordinator position:

Source tells @NFLonFOX that Chan Gailey on @Browns radar as potential OC. Joins Marc Trestman, Al Saunders & John DeFillipo as candidates — Alex Marvez (@alexmarvez) January 12, 2015

Gailey and @Browns GM Ray Farmer also were together in Kansas City in 2008 so Ray can speak to Chan's ability first-hand. — Alex Marvez (@alexmarvez) January 12, 2015

Gailey has a long coaching background, but most recently, he was the head coach of the Buffalo Bills from 2010 to 2012. He went a meager 16-32 as the Bills' head coach. I won't profess to be an expert of Gailey's offense, but he would reportedly maintain the zone-blocking scheme and implement the spread offense. He has been out of the league for two years, though, so he'd have a little bit of catching up to do.

Also, don't be surprised if one of the candidates the Browns interviews for their offensive coordinator position ends up becoming their quarterbacks coach. I speculated that about Matt Cavanaugh last week, and Marvez made the same point with John DeFilippo.
