Dane has hitched his wagon to Izzo at MSU as the coach in waiting when Izzo retires. If Izzo refuses to retire like Boeheim, Dane could be waiting a long time.I don't think Michigan fans would be thrilled if it happened, but I do believe Dane Fife would be both a realistic and excellent hire.
I don't see Billy Donovan taking the job unless he was offered Calipari type money. Brad Stevens isn't leaving the Celtics. I highly, highly doubt UM would wade into the mud for Rick Pitino. Other than that, there aren't any other realistic choices among the elite level head coaches.
