Indianapolis Colts running back Josh Robinson is now expected to be the RB2 behind Frank Gore. The Colts recently waived/injured projected backup Boom Herron. Vick Ballard is also dealing with a hamstring injury and is forever injured. This leaves Robinson as the primary backup to Gore.
Fantasy Analysis:
While Robinson may have been given this job due to injury, he's also the most talented running back on the team other than Gore. The rookie has impressed all offseason and in training camp. He should be considered the top handcuff for Gore and probably was before Herron got hurt too.
