The Raiders struggled on defense at various points last year and it's not entirely clear whether the Raiders will have any of 2012's starting linebackers other than Miles Burris back. Two of last year's starting linebackers - Phillip Wheeler, Omar Gaither - will be free agents in March if the team doesn't resign them before March 12th.
The other starting linebacker, Rolando McClain, is a likely cut this offseason.
The team is also potentially moving to a 3-4 alignment. In that scenario, Burris would likely move from weakside LB, where he played in the 4-3 alignment, to inside linebacker in the 3-4.
The team, therefore, will be in the market for linebackers - both outside and inside linebackers.
Here is a look at the top prospects in each category in the 2013 NFL Draft:
1. Chase Thomas 6’4 250 lbs Stanford
Thomas is far from flashy as an athlete, but he more then makes up for it with great technique and motor. With a great first step and and good hand useage, he can bend the edge and has a good array of moves to get to the QB but he needs to add a power move.
Thomas is a good run defender, able to get his arms extended then shed blocks to make the tackle but he can get overwhelmed by better tackles and run at. He might not have the upside of others but has more refined technique.
Pro Comparison: Connor Barwin
