Running back: Dalvin Cook, Alexander Mattison, Mike Boone, Ameer Abdullah, C.J. Ham (fullback)
Analysis: Cook is clearly the starter, but due to his injury concerns, it makes sense to have plenty of depth behind him. Mattison is a serviceable backup, as is Boone. Abdullah is more of a special teams player, but he can still serve as a different dimension in the offense if need be.
