We've all discussed this at length, but before he signed his extension I thought he could be gone sooner rather than later. After he signed it, all sources and information indicated strongly that he was committed to ND for the immediate future. I think the NFL is an itch he will eventually want to scratch, and we should cross that bridge when we come to it. I really, really doubt it has anything at all to do with coordinator hires and I think some people try very hard to link everything to Kelly => NFL.
I could see Quinn coming to ND if we're willing to pay substantially more than Buffalo. Simple fact is when Quinn originally went to Buffalo, Notre Dame was not positioned to pay him a top tier OC salary. Now our pay is much more competitive. I don't think Quinn ever intended to be at Buffalo long term, he just badly wanted to be a HC and get that experience. Now he's done it for 4 years and he's probably looking to move up. Notre Dame can potentially offer both more pay AND a better stepping stone to a middle-tier job like a UCONN, Pitt, etc. than Buffalo. So I don't really think this is a big longshot, and I realllllly doubt he would go through the process of interviewing if he wasn't legitimately interested and considering it.
