If he's healthy, I say yes. Further, I say unleash him in the running game. He's the most feared runner in the B1G, if not the nation when he's allowed to. So, I say dial up some QB runs for #5. Not all the time, mind you, but not sparingly either. Urb said they only had 2 called QB runs in the Buffalo game. I know the fear is he might get hurt if he runs too much, but he also brings a dynamic to the offense that isn't there when he's not running the ball. KG is a good enough backup to risk it, IMO.
Unleash the beast.
