Nutt ran a pounding running game with McFadden and Felix Jones and benched Mustain for Casey Dick. It was not a Gus Bus offense. It was all Nutt. Gus realized he had been used by Nutt to get Mustain and Williams and they all bolted after 1 year. And Gus was way out of his element this year with 2 pounding RBs - which is why Lashley started calling plays. Then amazingly, their offense comes together. Gus is a 1 trick pony.
