Nards is a different cat.
He stuck at MSU for a long time, didn't jump at the first job.
He is a genuine guy and he also is a cultural fit at Pitt, he grew up in the region and has a real affinity for the city and school.
ND, if they came at him and offered a boat load of money, IDK, that would be something he would have to think about.
As long as the admin remains supportive, he is being paid reasonably and the coaches and other aspects of the program are funded, I don't think he goes back to MSU even if they come at him hard.
That said, people are right about D'Antonio. He is a LONG way from being in trouble.
