Here is a way to simply take away any claims. Give officials of all levels similar opportunities, then these comments go away. Until you do that, you will have these claims.
There was a claim a few years ago by a coach that said the officials were not Black. Then the state started putting officials in situations to take away that claim.
I do not know the situation here, I do not know if the claim is valid. But when you have a sport where many of the top teams and players are of a certain race and you never schedule officials that look like the participants, then you have these claims.
There was a nationally televised game on TV a few years back with three Black D1 Officials. It was such an unusual thing in this particular conference. I sent a text message to one of the officials working the game showing how surprised I was by this occurrence. He responded to me, "Hey, we thought the same thing."
