I think if coaches spent more time talking to the officials (off the mat) they would find that the officials are humans too.

Yes they can make mistakes, but they are not "out to get you". If a "judgement call" was made, ask about it after the match. It will not be reversed, not matter how much you scream and yell.

Also, your wrestler is waiting on the mat, while you are making a "donkey" out of yourself.

Sportsmanship is learned best by example - set a good example for your wrestler and the sport.
