Brian Kelly has made the odd decision to buyout the last year of his $3.2 million contract and test the free agency waters. Considering Kelly is 32 and has missed 20 games over the past two years because of injury I doubt he will get the big payday he hopes for. Kelly's best chance is to go for a multi-year contract with a decent signing bonus.
While this appears to be the perfect chance to resign Kelly at a lower price, Kelly's squabbles with Bruce Allen. Last offseason Kelly skipped voluntary workouts because Allen refused to negotiate a new deal. Seeing as how this came right after Allen negotiated a new deal with Ronde Barber you can see how Kelly would be miffed.
For next season the Bucs should be in good shape with Phillip Buchanon starting in Kelly's place, which worked pretty well for the Bucs last season. Although the Bucs should consider drafting a corner to eventually replace Barber, and in that vein Buc'Em has a list of the corners in the draft.
