The athletic put out a list of 30 coaches in college basketball that they think are destined for bigger things (not a ranking, ordered alphabetically). Two notables for Michigan fans, Patrick Beilein and Luke Yaklich. I want to see JB stay as long as he can, but it certainly seems he has built a nice coaching tree so there should be decent options when he does decide to retire. Link included for anyone with a subscription to The Athletic.
