I don't think Gray is that great at receiver but the kid can run. Plus when he is given the ball the D could never be sure he wasn't going to pass so D backs would have to stay back giving Gray more room. Gray could also circle out of the backfield to make a large, outlet target for Shortell. For those who say Gray is too tall I think J. D. Pride who played with Tony Dungy was also very tall. At 245 pounds he would have a lot of power inside, the size to block linebackers and the speed to break some long runs.
