you've got some great options here. i don't think it would hurt you to start any of these guys.
with charles potential, i don't think you can ever sit him.
i think torain had his best game of the season last week and he's banged up so he's out.
i'd say hillis is probably the guy as you can't argue his numbers. he even had an admirable day against pittsburgh.
starting benson won't hurt you though. he's all rested up after the bye.
