I wonder if the conference has defined "storming the field." Some are obvious. Like the ones we see when we lose on the road.
Others, not so much. Suppose it's not the whole field, but only a hundred or so students. Suppose it's only a few drunks running around like headless chickens.
I agree that a $500K fine won't stop it. Which probably means stiffer penalties -- maybe moving what would have been a home game to the opponent's field -- which is not only a competitive disadvantage, but a huge monetary penalty for the school and the local economy. More severely, forfeiture of the game.
Regardless, as penalties become more severe, the exact definition of "storming the field," will get interesting.
