They were feral animals...even back in the early 70's.
We are playing "Pearl" high school, one of the black high schools in Nashville. We both had good teams and to make this short, we kicked a 50 yard field goal to win as time expired. The place erupted. We kept our helmets on, bottles ( they were glass back then) were flying, their players and fans were the essence of feral beasts. Pearl did not have enough security but our principle was smart enough to have security, which literally huddled us together, formed a wedge and knocked people out of the way....it was frightening. Of course, our fans did not have security and there were fights, standoffs, it was a mess. We had bleeding fans, cops called in, ambulances and as we left, our bus was pelted with bottles and rocks.
Our predominately white high school took the brunt of the blame. Yes, it was our fault the feral beasts acted like feral beasts. Nothing has changed in 40 years, other than now, the beasts are emboldened even more ( if that is possible) because one of the racist own is in charge.
