If he's staying at (going back to) Winthrop, then I don't think Mack to IU is in play now or even potentially in play when X's season is complete.
This whole thing has been really messy. In the end, as much as I love Kelsey, his reputation probably takes the biggest hit. Short of
Xavier should Mack ever leave, how many other schools will look past this incident the next time they're looking for a coach.
