'A running back hasn't been drafted in the first round since the 2012. That could change in 2015 with a group of backs that looks as deeper and more talented than either of the last two seasons. But some of the top players have injury questions. Georgia's Todd Gurley is coming off a torn ACL, while Indiana's Tevin Coleman is expected to skip workouts with a foot injury. In such a crowded class of backs, injury evaluations and workout numbers could be enough for a few running backs to separate themselves.'
