Report: Eric Mangini on Raiders' radar again

New Oakland Raiders coach Jack Del Rio is considering Marc Trestman and Bill Musgrave for the offensive coordinator job, and the NFL Network has reported that Del Rio is also talking to former NFL head coach Eric Mangini about running the defense.

Mangini interviewed with Oakland this month for the job Del Rio eventually landed. Mangini was the 49ers’ tight ends coach in 20014, but his history is on defense. He was an outstanding coordinator before becoming a head coach with the Jets and the Browns.

Former San Francisco defensive coordinator Vic Fangio has been linked to Oakland as a candidate for the same job, along with former Atlanta head coach Mike Smith, who worked for Del Rio in Jacksonville. Fangio also is interviewing in Washington, and Friday there was a report out of Washington that Smith might be unlikely to join Oakland's staff.

Trestman was reportedly interviewing with Del Rio Sunday, and ESPN’s Chris Mortensen reported that Eagles quarterbacks coach Bill Musgrave is a serious candidate for Oakland's offensive coordinator job as well.

The NFL Network also reported that the Raiders asked Denver permission to talk to offensive coordinator Adam Gase about the same job. Of course, Del Rio and Gase worked together the past three seasons with the Broncos. The NFL Network has reported that five teams are interested in Gase.

Kyle Shanahan was on Del Rio’s list at offensive coordinator, but he reportedly will take the same job in Atlanta. The only known coach Del Rio has hired is offensive line coach Mike Tice. He was most recently in Atlanta and worked for Del Rio in Jacksonville.
