Reggie McKenzie and the Oakland Raiders tried to address the linebacker position via the draft by selecting Marquel Lee in the fifth round and also via free agency by signing Jelani Jenkins, but middle linebacker is still a glaring hole on defense.
All in all, the positional group is still pretty murky. Even if Lee and Jenkins start, which seems likely at this point, the rest of the unit includes Tyrell Adams, Neiron Ball, Shilique Calhoun, James Cowser, Ben Heeney and Cory James.
Last year, veteran Perry Riley Jr. was signed off the streets in the early parts of the season, and added surprising stability to the group.
