Williams will win the job again in camp.
Williams will struggle to hold onto the rock because his problem is he cannot secure it when fighting for extra yards, and his ability to fight for yards is his strength.
Rams will turn to Corum and Hunter by midseason.
Corum will do well but won't be able to bust big gainers.
Hunter will take the job thereafter, probably late Nov or early Dec. RB is one of the positions that translates quickest to the NFL, the run reads are easy and instinctive so they just have to grasp the protections and be willing to make that sacrifice.
