Arkansas fans vehemently disagree. He's not a great coach and he's crooked as a dog's hind leg. He's widely considered a scumbag in Arkansas. Remember, they paid him $2 million to "quit" without any restrictions on where he could coach. They clearly didn't want him and hoped that he would land somewhere else in the SEC... to ruin a rival's program.
I don't care for Petrino but he inherited a cupboard more bare than Kiffin did because of Nutt. Like CLK, he came in and re-established discipline that was way out of control.
