Putting aside the Minnesota opening and this Hallman character, we should acknowledge there is a problem. Most players are black and I read an article that shows 59% of assistant coaches at the P5 level are black. It's not really a pipeline issue - in another thread, someone talked about an analogy of women in engineering. That's a pipeline problem because far fewer women go into that field - that is not the case here.
Now we're (likely) going to have 0 out 18 head coaches in the B10.
Again, take the Minnesota job out of the equation. I am not advocating taking a black coach just for the sake of it, and I don't really see a lot of realistic candidates. But why is that? If 59% of assistants are black, and that's the main talent pool for getting a D1 (not P5) head coaching job, it stands to reason that there'd be more black head coaches than there are. I do not understand, nor do I know what would work better.
