He has stated numerous times he has no interest. He just signed a 7 year deal, and word has it RU is already adding more money to it.
His wife does not want to move again (which she has stated publicly), and Schiano already turned down the Miami job before he left for RU.
Also, a recruit who I am not going to mention stated he asked GS if he were leaving, Schiano told him absolutely not, that he's here to stay and RU can win a NC. One thing about GS is, is that he's brutally honest, and would not lie to a kid.
