It's Gus' offense and that is how they have been winning games.
Any chance GB takes a big chance and goes with Malzahn as HC. It would be a risk, but I think the writing is on the wall with this guy, he is an offensive genius. Someone is going to take a chance on him and be successful.
He would need to hire a strong Defensive Coordinator, and a strong staff that could recruit, but I think it would be a gamble that would pay off.
