Looking for an inside linebacker in free agency? You’re in luck. The top three unsigned defensive players in PFT’s free agency rankings — Brandon Spikes (Buffalo), Rolando McClain (Dallas) and Mason Foster (Tampa Bay) — are all inside linebackers. On offense, there are still some decent options left at wide receiver, with Michael Crabtree (San Francisco) and Hakeem Nicks (Indianapolis) among the best of the rest. And there are a few starter-caliber offensive linemen left, too, with center Stefen Wisniewski (Oakland) and right tackle Joe Barksdale (St. Louis) among the headliners.
