From Rivals at U.S. Army Game practice -
Green is a bowling ball of a runner who is very strong North-South but has quick feet and good balance. Once he decides to hit a hole, and he is a decisive runner, he is a load to handle. It would have been nice to see some full contact because you could tell he would have shrugged off linebackers. Green ran hard and with excellent straight-line speed.
I really doubt any freshman will contribute at RB in 2013.
