I agree that the Vikings have a good run defense. But, if you watch Reggie run the ball in any game this season his forward progress stops as soon as someone touches him...literally, just a touch. The best example was in the second half last night when they ran a sweep to the left side of the offense. The CB ran up and bumped Reggie on the shoulders with his hands; Reggie stood up and trotted out of bounds for no gain. That happens a LOT with him as our only RB. Deuce would have no problem lowering his shoulder and making someone earn it, and he would at least fall forward and get a yard. Our run game isn't sustaining drives and Deuce is the guy to keep them going.
Injuries are hurting the team right now, but with half of the team on the DL, why not play your best RB? Makes no sense to me.
