5 biggest losers of NFL free agency

4. Oakland Raiders

Jon Gruden’s return to coaching has turned the Oakland Raiders into both an active team in free agency as well as blasts from the past. They have spent much of the past week bringing on a collection of questionable veterans, such as running back Doug Martin and wide receiver Jordy Nelson, while moving on from younger talents like Cordarrelle Patterson (traded to the New England Patriots).

The Raiders have reworked their secondary, but have also aged it: Cornerback Rashaan Melvin is the youngest of the three new key additions at age 28; cornerback Shareece Wright is 30 and safety Marcus Gilchrist is 29.

But perhaps nothing showcases just how long it has been since Gruden has served as a head coach than one of Oakland’s most recent signings: quarterback Josh Johnson, who will serve as backup to Derek Carr. Johnson hasn’t played an NFL snap since 2013, but that must not matter to Gruden, as he helped draft, and then coached, Johnson in 2008 when Gruden was at the helm of the Tampa Bay Buccaneers. The Raiders will have to rely on the draft to add youth all along the roster.
