Colts RB Trent Richardson underwent shoulder surgery following the season, per source. Told it was “just a scope.” Shouldn’t hurt offseason.
Even if Richardson is handed the starting gig in Indy, there's no guarantee that he won't be passed by Vick Ballard or another back by midseason. That goes double if the Colts re-sign Donald Brown. T-Rich just hasn't looked very explosive since entering the NFL.
