Not sure why you're comparing Big East/Big Ten. Xavier isn't in the Big Ten. And Xavier and Michigan aren't same programs. Comparing conference records during an arbitrary timeline is silly.
Every coach is flawed. But I think Mack would be a good coach any michigan because He has been a success there and Xavier coaches have translated very well to high major jobs. You don't want Pitino because he hasn't shown he's anything more than a below average coach. Mack has proven himself to be a good one.
I would take any of those three as well. But I don't think Marshall would go anywhere. Hoiberg's timeline might not match up with Michigan's as a coach isn't going to drop down from an NBA job by choice.
