He is averaging over 13 yards per carry. He hasn't passed very often because he hasn't needed to. Many pass plays don't gain 13 yards so why pass?
I believe the Collinwood game is the only game that he has played the entire game. In the loss to Giles County he did not play the second half. Didn't need to chance an injury to a 3A team. In the loss to Ezell Harding, he was having really bad cramps and couldn't finish the game. In all other games he was through by halftime or after three quarters because of the score. One game he only had 3 carries because he scored on each carry.
He is more of a running back playing quarterback. Mr. Football gives an award for the best back. It doesn't distinguish between quarterback and running back.
