It was revealed today by GM Chris Ballard that RB Marlon Mack played with a torn labrum during the entirety of his rookie campaign, and that he is currently recovering from offseason surgery. There was no timetable provided as to when the surgery took place, but Ballard believes Mack will be ready by the time training camp starts.
The running back depth chart in Indianapolis is thin with proven commodities, with Robert Turbin as Mack's main backup. That puts a bit of a spotlight on fourth-round pick Nyheim Hines. Hines ran a 4.38 at the Combine, and broke out during his junior campaign at North Carolina State, rushing for 1,113 yards and 12 touchdowns. He was also involved in the passing game, catching 89 career passes. At this point, we know Turbin doesn't possess much upside, so if it appears that Mack is slow to recover, you might want to consider Hines as a late-round fantasy option when draft season rolls around.
