Hard to say if he was a good WR corch or not. I've been told by a couple of coaches that the passing scheme in Malzahn's offense is nothing short of awful. If the running game is kicking ass, it looks great because play action is always there. But if we were behind and had to air it out to play catch up, we'd be hard pressed to score.
If you recall, Ricardo Louis pretty much said he'd have to learn how to run real routes when he went to the NFL. He tried to back track later but he had already indicated what they were doing at AU was pretty simplistic.
