"So I deem it intentional *(and thats where it all started since NO ONE knows what an Intentional is)...
One coach from B comes onto the court and says (hold your laughter)... Hes calling too many fouls!!! Thats not a foul!!! Get him off the court! So I begin reporting it to the scorer (who really isn't keeping score or fouls until I asked him too) and continue on... 2 shots made. We move on."
Why didn't this coach also get a T?
It is likely, that this set the bar that the other coach did not even reach.
As for working with inexperienced partners.
Talk whenever you get a chance during the game.
Do not start reffing the entire floor. Expand your coverage some, but only reach for stuff that needs to be called, and talk about the rest when you get the chance. Keep the game safe, but don't become robo ref.
