Actually, Malzahn does run a no huddle but it is a balanced attack. Malzahn left Arkansas because Nutt and the Hering (DC) were disrespectful towards him. It was widely rumored Hering would only refer to Malzahn as "high school". Also, Nutt was HC and OC his entire time at Arkansas until he was forced to hire Malzahn. Nutt didn't like it and never gave Malzahn full reign. So, Malzahn leaving had more to do with Nutt being a dick rather than offensive philosophy.
If MSU had any shot at Malzahn as OC, we would be stupid not to take it. I am not sold on him being a HC just yet. However, if we had no other attractive experienced canidates, I would gamble on him as the HC if I was Bryne. The guy has won every where he has been.
