The Bucs have announced the signing of its sixth-round draft pick, former Alabama running back Kenneth Darby. The terms of the deal were not disclosed.  Darby didn’t have the best of senior seasons, as he slid to the 6th round.  Playing for the Crimson Tide he has solid size at 5-foot-10, 211 pounds but does not have breakaway speed.  He is described as a more of a between-the-tackles runner.
