As much as I like Narduzzi, I tend to agree with you. In today's version of college football, I'll take the offensive genius as HC over the defensive genius every time. Tom Hermann was a slam-dunk, can't miss hire.
The flip side is that a guy like Hermann would never stay at a place like Pitt for more than 3-4 years, and he's biding his time at UH until the exact right job opens up. I do think Narduzzi is a good coach, he has a good plan, and the MSU blueprint does work, although not nearly as quickly. it requires recruiting and player development, something Narduzzi hasn't had the time or chance to succeed or fail at yet. I think he stays with us unless and until the MSU job opens up, at which time he would almost certainly be MSU's top choice. He would be a seamless replacement for Dantonio and MSU would pay handsomely for him.
