these RBs is ruined once they get 400+ touches in a season.....you seen it with Larry Johnson and Jamal Anderson and Jamal Lewis and now Murray
Human body ain't built to take the hits RB take at that rate and just keep it movin....you running into 300 lb D-lineman and 260 pound LB play after play that shyt gonna take a toll.
He ain't a great fit for philly scheme because he don't make guys miss in the open field very well, but I still don't think that's the only problem with Demarco.
