All four of our RB's have a chance. They are uniquely different and when healthy have game.
My guess is Clayton is not 100% so it's hard to say. The best guess on DL is Domineck right now.
I would definitely say that Juanyeh has a good chance and a year or two ago, Tariq. Sometimes we just don't know what's going on back there, who's trying to cover for other mistakes, etc. Trey Swiling may be less than 100% too and he might get a look. And athletic smaller fast nickel backs are needed so you never know with others.
Harvin is not consistent enough.
Williams is the most likely to make it based on his freshman season.
Brown is definite.
Chimedza and Ryans may get a chance down the road.
