With the Raiders recent acquisition of Kamerion Wimbley a good deal of questions have rose:
What will his role be on the defense?
Was he brought in to play linebacker or defensive end?
Could the Raiders be switching to a 3-4?
Some people have suggested that since Mike Haluchak(Raiders current linebacker coach) was Wimbleys' linebacker coach in Cleveland that means Wimbley will be playing linebacker in Oakland. Likely on the strong side. Others have suggested that this also means the Raiders may be switching to the 3-4; since Haluchak coached a 3-4 in Cleveland.
Wimbley is an interesting prospect to play linebacker. He has great size for that position at 6'3'' 255 lbs at great athleticism posting a 4.61 40 in the 2006 combine.
By some accounts, he is too small to hold up in the run as a defensive end and his athleticism would be wasted there. So he would be better suited to play linebacker.
And the 3-4? Sure it could happen. Tommy Kelly and Richard Seymour could play defensive ends while Trevor Scott and Kamerion Wimbley could be outside linebackers. Then all the Raiders would need is someone to play inside linebacker and nose tackle.
I believe both cases are unlikely.
First off just because someone came from a 3-4 doesn't mean they will play the same position on a different team.
John Marshall and Mike Waufle are other examples.
John Marshall, Raiders defensive coordinator, has predominantly coached 4-3 defenses and has done a very good job. Waufle, Raiders D-line coach, on the other hand has exclusively coached the 4-3 and done a very good job for the Giants.
Furthermore, Kamerion Wimbley is a natural defensive end. In college he played defensive end and he did a very good job. He did such a good job that it warranted a 1st round selection in the 2006 NFL draft.
Most likely Wimbley will play the same role as those before him like Greg Ellis, Derrick Burgess, and Kalimba Edwards. He may become a pass-rush specialist in the Raiders 4-3.
