Personally, I think that you need to realize that you are not doing "kiddie ball" anymore. This is college ball so simply, answer the first couple of questions then tell the "kiddie ball" coach "Okay Bill, it's time to get back to the game.", turn and walk away. The next time he approaches for a piddly complaint, hold up the stop sign and don't allow it.
He played you very well because he saw that you didn't have the gonads to stop him. I know that the NCAA is becoming little girls with all of their "let's huddle", "let's get the call right", "let's hold hands and talk" BS. Stand on your two feet and umpire.
Don't forget to take 2 TUMS and call me in the morning!
