TDs have to enforce a standard of conduct by teams, coaches, players, parents (spectators), and umpires. Post the rules of conduct in the information packet. That is their warning!!! When it occurs, there should be no surprise when they are escorted out of the complex.
There was a catcher that we played against at Compuware that made 3 great plays against us in ITB. All of our coaches congratulated her on an excellent performance. To me, it doesn't matter whose team you are on, if you shine, I'll always congratulate you. That is respect.
