I also suggest Wheatley but here's my strategy on back up RBs. You first have to look at when your stud RB's will be on bye or facing NE, Dallas, Balt., Car. or another elite run stopping defense. Then you look at who your options at Running Back will be playing. I would favor Travis Minor against ARI over Wheatley at N.E. cause I would only be playing Minor that one week. (Okay Minor is a lousy example, but you get my drift I hope.) Good luck.
