The Tampa Bay Buccaneers have added two players to the roster at two positions of need. Both running back Robert Hughes and safety Ron Girault were signed to the roster today according to the Bucs' own twitter feed, after participating in mini-camp on a tryout basis the past few days.

Ron Girault played college football under Greg Schiano at Rutgers, and entered the draft in 2008. He went undrafted and has never played a down in the NFL in the past four years. He did play with the Las Vegas Locomotives of the UFL last season. Girault sounds like camp depth to me.

The same can be said for Robert Hughes, although he has a better track record. Hughes played at Notre Dame from 2007 to 2010, amassing 1,392 yards on 321 carries in four years there. Most intriguingly, he also caught 43 passes for 370 yards. He was undrafted last season and spent preseason with the Chicago Bears, getting 16 carries for 69 yards and two touchdowns and catching two passes for 26 yards in the preseason finale. Despite that performance, he did not make the Bears' team or even practice squad.

It would be a surprise if either player made the regular season roster, but they should at least provide some competition at two positions of need.
