would Bush be better used as a WR like Steve Smith
I think he would be better used as a flanker lined up off the Tackle or TE. The defense would have to worry more about him in that spot than with him lined up outside.
He would have a LB covering him more often, he could float to the middle of the feild on Play action and have space to run, he could still be used as a decoy on counter and reverses, and he could get to the deep flat with the receivers going on a clearing route, he could run the cross "pick" route and have space to run.
Basically, I 'd like to see them take bush out of the RB position until he gets some time adjusting to the NFL and accustomed to the speed of the players.
