Carolina Ref,
You had it right. It's called good defense on the part of Blue... White loses.
Next time you'll know. "Gentlemen, you are wrong. It is a back court violation because White touched it last. I'll prove it to you after the game. Now what do you want me to do? Suck it up and look the part of the dummy in front of both coaches and all of the crowd? Or do you want to back off, shake your head in agreement, and let me make my own calls."
OR
"If I change my call (politically correct now that you've both felt the need to approach and have me change the call) and then later, I show you that I was correct, I want both of you to contact both coaches and tell them that you were wrong and I was right. Good deal? Infact, I want you do do that anyway. My call is correct."
Yeah, like that will go over good.
