Six years after leaving the franchise he helped turn into a Super Bowl contender, Warrick Dunn is coming back to the Buccaneers, as reported by the Associated Press. The three-time Pro Bowl running back signed Monday with the Bucs, who needed to bolster their running game because Carnell ?Cadillac? Williams missed most of last season with a knee injury. There are also lingering questions about when Williams will be able to play again.
