Fox Sports is reporting that new Raiders coach Dennis Allen has decided to retain running backs coach Kelly Skipper and that he interviewed Greg Manusky for the defensive coordinator position held by Chuck Bresnahan last season. Manusky, 44, has spent 11 seasons coaching in the NFL. He was the San Diego Chargers defensive coordinator last season, until he was dismissed by head coach Norv Turner at season’s end. Before that, Manusky was the defensive coordinator for the 49ers from 2007-10 and coached linebackers for the Chargers (2002-06) and Washington Redskins (2001). Source: Oakland Tribune
