According to a report from NFL Insider Chris Mortensen (via Bill Williamson), the Oakland Raiders are targeting Eagles quarterback coach Bill Musgrave for their vacant offensive coordinator position. Musgrave is reportedly a "hot contender" for the job. The Raiders are in the process of assembling a staff under newly-hired head coach Jack Del Rio. Musgrave served as Jacksonville's offensive coordinator from 2003-2004 while Del Rio was the head coach of the Jaguars.
Musgrave joined the Eagles as a quarterback coach during the 2014 offseason after being fired as the offensive coordinator of the Minnesota Vikings. He oversaw an Eagles quarterback position that led the NFL in turnovers with the play of Nick Foles and Mark Sanchez. To blame the Eagles' QB struggles on Musgrave would likely overrate the value of a position coach, but it's hard to say how much he helped matters.
This isn't the first time the Raiders have shown interest in an Eagles coach this offseason. Oakland interviewed Philadelphia offensive coordinator Pat Shurmur before eventually hiring Del Rio.
If Musgrave leaves for Oakland, the Eagles will have lost their quarterback coach for the second year in a row. In 2014 it was Bill Lazor who was hired by the Miami Dolphins to be their offensive coordinator. There was indication that Foles and Lazor didn't exactly see eye to eye.
No word on who would potentially replace Musgrave. There doesn't appear to be a natural in-house replacement waiting in the wings.
