When asked about the Colts' running game heading into 2014, beat writer Mike Wells had this to say:
"You would have thought this would be a no-brainer when the Colts acquired Trent Richardson from Cleveland. But as everybody knows, Richardson never found a comfort zone with the team. It’ll be a wide-open competition for the starting running back position. Vick Ballard, like receiver Reggie Wayne, has to prove he can regain his form after suffering a torn ACL. Don't be surprised if Donald Brown decides to test the free-agency market to earn more money and a bigger role on a team. He'll likely start behind Richardson and Ballard on the depth chart if he re-signs."
The only surprise here is that Wells believes that Donald Brown would start third on the depth chart after he (vastly) outplayed Trent Richardson in 2013. If this is the case, it's doubtful that Brown will re-sign. He has earned a shot at a starting gig somewhere (or at least as a back that will get a dependable amount of touches).
