I've only seen two in person. 1. was a little brawl between GT and Duke at the 2018 football game. Just some chippy play that led to some pushing and shoving, was broken up quickly. 2. Also in 2018 was in my section, Miami was in town, and I sit in CL4, which is next to the visiting fan section. Their fans and us talked **** all game, and an old couple of Tech fans nearly fought a guy, but it was broken up. At the end of the day Tech won, and all those Canes were shut up. (Miami fans are the WORST in the ACC imo.)
