I agree with the whole "Only answer questions" comments, but IMO it doesn't really help out. It seems you are asking HOW to respond.
Again, that varies by the individual. I can get away with more flippant comments b/c that is who I am. Others, can't. FWIW, I would try to develop 'Stock" phrases to use. Those are very good to use, especially if you can use language of art. For instance:
They can Hot Stove, but that is it.
The player was/wasn't legal
You may be right, we'll talk about it
My partner had a better look at that play than either of us.
My partner obviously saw something you/we didn't see.
I had the same call
THe player did/didn't displace them.
and my favorite -
Coach if you talk to me we can have a conversation. But if you keep yelling at me I am going to treat you like I treat my wife when she yells at me. I ignore her.
