After a quiet couple of weeks, there is some movement on the Oakland Raiders coaching front.

The Contra Costa Times is reporting that the Raiders have interviewed former St. Louis head coach Mike Martz for their open offensive-coordinator position. The paper also reported that Eagles assistant Juan Castillo interviewed for the open offensive-line job.

The Raiders fired four coaches, including offensive coordinator Greg Knapp, a day after their 4-12 season ended.

Martz believes in a wide-open offense that could fit the Raiders’ fast receivers. Yet, he has not coached in the NFL since he was the Bears’ offensive coordinator in 2011. There will likely be more candidates.
