The NFL Scouting Combine is over, but the Oakland Raiders are just getting started.
NFL Media Insider Ian Rapoport reported Monday that after signing punter Marquette King to a long-term deal, the team has shifted its focus to Donald Penn.
The Raiders hope to lock up their veteran left tackle to a long-term deal, knowing that Penn will be coveted on the open market once the Buffalo Bills franchise tag bookend Cordy Glenn.
He's no spring chicken, but Penn logged a solid season protecting quarterback Derek Carr, a campaign that saw the 32-year-old blocker start 16 games and finish as the 10th-ranked player at his position, per Pro Football Focus.
The durable Penn hasn't missed a start since his rookie season in 2007. Oakland's pursuit of him only highlights how tough it is to find reliable help at left tackle in the NFL.
