Kenneth Darby

Darby enters training camp with a real shot to become the No. 2 back behind starter Steven Jackson. His main competition will be Antonio Pittman who is a better pure runner but Darby's pass catching and blocking ability is better and should give him the edge, especially since the back-up will probably see the field only in 3rd-and-long situations. Even if he gets the job Darby isn't expected to be a fantasy threat unless Jackson goes down because the guy is a workhorse who will rarely come off the field.

Darby, a 2007 seventh-round draft pick from Alabama, spent most of last season on the practice squad before getting some playing time in a meaningless Week 17 game while the regulars were rested. He'll compete for a reserve halfback and special teams role.

Darby, the only skill player taken by the Bucs in the 2007 draft, could challenge Michael Pittman for the role of third-down back this season; that's a longshot, and that would pretty much be Darby's upside in the pros.
