Last week after a second-quarter fumble by Doug Martin Barber came into the game and out-touched him 10-0 for the rest of the game. Martin is a veteran and has been a Buccaneer his whole career, and I doubt he gets benched indefinitely or for the entire game, but the Bucs have to see what they have in the younger Barber.
On the season he has outpaced Martin in yards-per-carry by almost a full yard. With the evaluation mode in Tampa in full swing, they have to see just what they have in the younger players and Barber might be the best of the bunch.
Since the failed drug test from Martin, the Buccaneers can release him, and it would cost them nothing. If they feel Barber would be a better long-term replacement or if they were determined to draft a running back this year it still makes sense to get Martin off the books and let Barber have the keys to the car as it were.
While the Falcons have improved some, they are still a team that is susceptible to the rush as last week was evident by all the missed tackles. Barber is someone who hits the hole hard and relies on brute strength at times to get his yards which could spell trouble for a Falcons line that might be without former Buccaneer Adrian Claiborne.
