Regardless of the Grossman vs. Beck QB competition, they're going to need that crop of RB's to scurry them down field. Or else their 3rd and out will move them backwards more often than not. I would say "If Shanny were smart he'd put a rocket on Hightower's back and shoot him towards the post routes". But all that is predicated on the "if shanny were smart" part... so it becomes wishful thinking.
