Free agent safety Reggie Nelson re-signed to a one-year contract with the Oakland Raiders, according to Ian Rapoport of NFL Network. Nelson was a Pro Bowler for the Raiders in 2016, but was graded as PFF's No. 78 safety in coverage last season. However, Nelson's first Pro Bowl in 2015 coincidently overlapped with new Raiders DC Paul Guenther's final season in Cincinnati. It is possible Nelson, going on 35, sees a resurgence in Guenther's system.
