Mark Weisman

Weisman would be ranked higher if his health could be guaranteed. The bulldozing former fullback ascended from the bottom of the depth chart in 2012, and in doing so made the fact that he was ever a backup at all an immensely puzzling fact. Weisman was a machine before dealing with persistent ankle troubles, pummeling Northern Iowa, Central Michigan, Minnesota and Michigan State for 623 yards and eight touchdowns. Weisman's bruising running style exposes him to a lot of hits, but he has RB1 upside when he's at full strength.
