To be fair, when I got Demps his carry was like 65-70. It took a while before I could even play him without fumbling. He sat behind Reggie last year for a reason.
Edit: For anyone wondering, it's at like 91-92 now.
He can't fumble if he doesn't get touched At least I haven't seen that in this year's Madden...though it would be hilarious...just be running down the field swinging your arm and suddenly throw the ball behind you. But yeah, I think the people who had success with him (Hemingway had him in Season 1...and had several big games with him before being called out on it and subsequently trading him) were able to call plays where he went untouched. He was easily equal to a Chris Johnson or somebody...but with a league minimum contract.
