These are kinda tough!
I'd go Stafford, Felix Jones, and maybe Percy Harvin.
I don't like anyone vs. the Steelers so Stafford gets the nod.
Felix Jones isn't competing for carries anymore and Beanie Wells is an underachiever who I'm not sold on.
Holmes won't get the looks in the past due to the new look defense of the Cowboys, I've never been sold on Collie, Ochocinco looks lost out there in the preseason (I heard he's having issues learning the plays in NE) and you don't know what you're going to get yet with Julio Jones.
I'd be careful with Percy due to his migraines, though.
