Vick Ballard was a nice surprise this year, racking up over 800 yards and running with power. But the rest of the backs had trouble staying healthy.

Injuries plagued Donald Brown once again. The Colts have to decide whether or not to stick with the former first round draft pick. Brown has awesome speed, but struggles with blocking at times and hasn't been durable. If they keep him, I hope he's used more in the passing game so he can catch the ball in space, where he can be off to the races.

Delone Carter was coming on in short yardage situations until he was hurt too. Carter has shown flashes of being a good running back at times, but still has something to prove. He must show that he can be consistent and hold onto the ball.

In the NFL, a team needs more than one reliable running back and the Colts will have to make some decisions in the off season.

Though the Colts could use an upgrade at most positions on defense and definitely on the offensive line — they can't have Andrew Luck being hit so much — depth at running back is something I haven't heard being mentioned.

It's not as glaring a need as offensive line and defense, but I think it's a bigger need than receiver at this point.
