The only fight I've ever had in a game was a brawl in the stands that spilled onto the floor during a HS boys game. Fortunately we were in a full time out when the fight started, it was opposite side from the table, and we were a 3-man crew and all of us were 6'1"/200lbs or bigger. All those things allowed us to keep the players from entering the fray.
Even more fortunately, about 6-7 armed, uniformed cops appeared practically out of nowhere in the first 30 seconds of the fight and they controlled it pretty quickly...2 or 3 arrests were made. The teams were from small towns about 15 miles apart who had a long and bitter rivalry. Dumba$$ drunks in the stands...what every rivalry game needs
I didn't like it.
