Colts' backfield competition

This offseason, the Indianapolis Colts shored up their running back corps by adding free agent Ahmad Bradshaw and drafting Kerwynn Williams in the seventh round. They join Vick Ballard, Donald Brown and Delone Carter. ESPN NFL Insider Matt Williamson ranked the Colts backfield fourth in the AFC South, though he is "quite fond of the stable that Indy has put together."
