Archie Miller, the Hurleys, and Mark Jackson are not coming to SJU. I would hope that whoever makes the call to replace Lavin (if/when he is replaced) would also commission an independent non-SJU committee to do the hiring or at the very least the recommending. To paraphrase Ben Stiller in Meet The Parents "SJU sucks at hiring basketball coaches."
There is no way SJU would entrust the decision to an independent committee. The best they can do is enlist some very knowledgeable retired coach(es) or AD(s) to guide them through the process. I wouldn't trust anyone who just had experience in the pros. If when this happens, it will be SJU spending the money, so they will make the decision, hopefully with guidance.
Somebody will have to buyout the last year of Lavin's contract. I think the very top echelon of donors will be asked to do that if they desire change. That's what happens at most programs.
My bet is that our donors will not do any such thing as buy out the last year of Lavin's contract, unless there is a reasonable buyout (500K or less). Our big donors I'm afraid will not eat a whole year of Lavin salary for nothing in return - if it came to that they'd simply wait and see what the final year turns out.
That would be my understanding as well.
