OK, never mind Bran, I found the answer.
I was thinking of Mike Vollmar, the former Director of Football Operations at UA. He's the one Pannunzio replaced, right?
He was the DFO at Michigan State when Saban was there as well as when Nuss was there as QB coach. I'm sure Vollmar and Saban have talked just as I'm sure Nuss and Vollmar have spoken.
My point? Nuss knows what he's getting into in terms of time, dedication, responsibilities, his "position," etc...
