Update on the Colts' RBs

One of the teams with a perceived need at the RB position at the start of this past offseason was the Indianapolis Colts, despite some encouraging work from Vick Ballard. It took a little time, but the team did finally add Ahmad Bradshaw, and in the time since, there's been a lot of conjecture as to how the new backfield rotation would work (and whether anyone would be cut). So as the Colts run through the early portion of the preseason, it's worth circling back on this topic.
