I myself could care less who wins the games. I'm out there to do a job, and I'll do it to the best of my ability. I don't believe in violence, but I do believe in defending myself, and I will do it in a violent and savage manner if I have to. My message to other sports officials is the same. Defend yourself the best you can, then take them to court.
Most people including coaches are great people.
The few exceptions would be better people if they got their teeth kicked in, or a long stay at the hospital, and a law suit to go with it. If a coach or a fan gets rough with you, give it back.
