Listening to reporters who have covered SU, it is clear that he changed the culture of losing in Syracuse and that he has the reputation for developing players. Ex: Chandler Jones and probably improving Nassib's draft position in April.
He was in demand, interviewed by Browns twice and the Chargers were preparing an offer and on the Eagles radar as well.
Will he be a successful NFL HC, who knows?
But for once I am glad the Bills are thinking outside the box.
