The Indianapolis Colts have upgraded their backfield in search of a AFC South title. Trent Richardson was traded to the Colts for a future first round pick on Wednesday evening. Richardson is in his second season after being taken 3rd overall by Cleveland in 2012. He has 1,055 yards and 11 touchdowns in his young career and ran for 105 yards on 31 carries this season. The Colts needed a running back after losing Vick Ballard to a torn ACL in practice last Thursday. Richardson joins Ahmad Bradshaw and Donald Brown in the Colts backfield. Bobby Rainey and Chris Ogbonnaya will split carries in Cleveland for the time being. Adding Richardson to Andrew Luck and Reggie Wayne make the Colts a serious contender in the AFC South and in a weak AFC.
