Wimbley, 26, has 26.5 sacks in four seasons of play to go along with a pick and 7 forced fumbles.
Drafted by Cleveland in the first round of the 2006 draft at No. 13, he played OLB in their 3-4 scheme. He played as a pass rushing down lineman during his college career at Florida State, however, and it appears that he'll play left end for the Silver and Black, taking Greg Ellis' spot on the end opposite a likely rotation of Trevor Scott and Jay Richardson, with Matt Shaughnessy able to play OLB and DE when needed.
I expect great things out of Kamerion now that he's back to his speed-rushing end position–people should remember that Derrick Burgess, a similarly statured speed rushing end, came to the Raiders and led the league with 16 sacks his first year as Raider and followed that up with 11 the next year.
This should prove to be an incredible front four now with Trevor Scott, Tommy Kelly and Richard Seymour. He only counts just a little over a million in salary, although his contract runs out at the end of 2010. The Raiders would do well to re-sign him before the season starts, however.
After a relatively quiet offseason so far, the Raiders seem to really have made a couple good moves lately (Wimbley, re-signing Gradkowski, etc) and while I don't think they should be satisfied, they definitely seem to be heading in the right direction.
