This situation is worth noting, but.... The Chapman - Miller situation, considering their tie-in with Friendship, one with a daughter that graduated from the school and a grandson that graduates this year (a FCS baseball player). The other is a guy that 5 years ago was an assistant basketball coach for FCS.
Needless to say, I don't think this was a mistake. It's as if it was planned... But regardless of a mistake or being planned, I blame Chapman. Most umpires just go where they are assigned. Maybe Miller voiced his concerns prior to the game, but ultimately it's the assignor's fault. The assignor should be reprimanded appropriately.
Sticking the proverbial "head in the sand" only means that abuses will continue, and kids will continue to be affected negatively. Do what needs to be done TSSAA. Send a message and make this assignor accountable! There are others in that group of umpires that can do better, much better. But if Chapman had any character, he would hide his head in shame and resign immediately.
