I believe that big boy sports at the Power 5 level, and up through the pros, should be past issues like this. Or a non-issue like this. At this level, money drives everything, and you make money by winning. You win by putting the best players on the field or on the court, regardless of skin color. You win by putting the best coaches in place, regardless of skin color.
When is the last time Auburn had a white starter on defense? Jake in his khaki's? Do you give a shit? Does that make one iota of difference to you? Of course not.
The same goes for coaches. As an AD or owner, if I feel like Coach A gives me a better chance to win over choosing Coach B, I'm going with Corch A and don't give a rat's ass about his skin color. Now admittedly, if clearly qualified black coaches are consistently getting passed over in the interview process, you may have a problem. But if I'm an AD or owner, why would I not want to interview any candidate who checks off all the boxes?
I think incentivizing the hiring of a black coach is an insult and slap in the face to that individual.
