I wouldn't base too much on on his decision making. AD will be just fine once he is on a roster... as we all know, he's a gamer and thrives in game moments... once he's given his chances, he will prove that.
I would think that at least two series would have been to showcase his running backs and offensive line in a power running game. This is an exhibition to display the attributes of the players. I don't think Sparano got that.
you have a whopping 12 rushes by RB's. Split between 5 guys. Way to showcase your roster, *******. Meanwhile over on the North bench, Blount, Miller and Bell combine for 24 carries.
