In defense of the fellow yelling "Snap their necks!":
I was also at the game and am not from either school, not even from a school in the same division. This was actually my first Division II game to watch all season; I consider myself to be objective, though don't we all...? Anyway, my assistant coach and I both heard the yells of the fellow you're speaking of, and were sitting quite close to him. He was yelling "Snap that net!" -- encouraging his team to score a goal. My friend and I then listened carefully because we'd never heard scoring a goal spoken of in that fashion (and thought it was really humorous); but it was clear that is what he was saying. He cheered his team on throughout the entire game (rarely using what I would call common soccer lingo). I also noted that this man only encouraged his own team's players. He never spoke a bad word about the referees or other team's players. There were some that did so, but nothing remotely close to "snap their necks."
