I Feel is a lot more silly here in the USA since these teams are all pretty much franchises when they were founded.
Unlike the majority of the rest of the world where at least in the beginning many teams were founded as amateur clubs from certain cities or regions therefore there was more of a deeper connection since man locals took part in it, and the connection that may have been passed on to other generations.
Though sometimes the frustrations of certain parts of society spills over to sports and causes fighting not because of the sport itself but maybe X team represents the "authority" or the "regime" therefore fights occur, and a million other reasons made up just to fight.
Still, like I said the only fights or scuffles I expect from this match are those influenced by alcohol
