I would say this is ridiculous but then again, we see how some sports teams supporters here in the US act if their team wins the national championship. Burning cars, bonfires, excessive drinking, damaging property. Over a friggin’ game? Srsly? It’s not like they were actually playing the game.
I’m sure that the Russian hooligans aren’t NBA fans but I would like to invite them to whatever city wins the championship. And tell them they are fans of the team that lost.
