Cowboys coach Wade Phillips believes that the running game will be a big factor for the team next season, and plans to use a three-back system. "If a guy can play and help your team in a certain role, you want to utilize him," Phillips said. "Not only for the team but also for the overall morale of the team that, 'Hey, I've got this role and I can help the team win,' instead of just sitting on the bench all of the time. They practice better. Everything, the chemistry of the team is better when more players contribute. I think we have that at running back." That means Dallas will feature Marion Barber, Felix Jones and Tashard Choice in the backfield.
