re: I just realized that South Carolina fans stormed Clemson’s field lol

I'm not sure exactly, but there is an article in the Athletic talking about goalposts being torn down throughout the history of college football and almost all of the ones torn down before 1970 or so seem to be when teams win on the road.

Here's a snippet:

Bringing down a goal post was not for the faint of heart.

"In 1929, Georgetown beat Richmond, so Hoya fans stormed the field. Richmond’s brilliant head of police had told officers to protect the goal posts — city property — with force. What one newspaper described as a “bloody battle” broke out, sending three students to the hospital with cracked heads.

Alas, the Richmond head of police had only thought to protect one goal post, and when the Georgetown students realized the other end was left unguarded, they ripped down that goal post and marched out of the stadium singing the Georgetown fight song."

Some times they were tearing them down at home, but it was to keep the other team from kicking a FG to win or tie and forcing them to score a TD. Crazy stuff.

I think it went from road games to neutral fields. Tearing them down in bowl games after winning a title and then eventually people started doing it in their own stadiums.

Northwestern students tore theirs down in the eighties after they broke the record for consecutive losses. No. not ending their record streak, but breaking the record. They lost the game and tore down their own goalposts.
