To be clear, the celebration that happened in Storrs after UConn's Elite Eight victory was not a riot, at least according to campus police. The scene above, which includes a mob of college students wildly screaming in front of a bunch of small fires might lead one to believe this was a riot, but no, this was merely a joyous gathering in front of cops (who actually seemed to get a kick out of it).
These particular students got their inspiration from the bench celebration that the team has been utilizing throughout the tournament.
When performed by the team, it's a pretty cool celebration. When recreated by hundreds of belligerent bros, it's... kind of terrifying actually, right?
