Biggest post-draft questions still to be answered by the Oakland Raiders:
Who's the middle linebacker? Ben Heeney and Cory James are the only returning players on the roster with heavy middle linebacker experience, and Perry Riley Jr. remains a free agent. His price tag may have gone up, even with the Raiders drafting Wake Forest's Marquel Lee in the fifth round. It's just hard to imagine a fifth-round rookie stepping onto an NFL field and starting right away, even if Lee did play the middle linebacker in a 4-2-5 scheme and had 7.
