As far as i can figure, Americans generally don't care for football/soccer because they aren't world beaters in it. I'd put money on it that many off these haters would be straight on here bragging.
It seems the USA has a good college set up, and although the most talented athletes are likely chasing the cash in the NFL/NBA. (i'm not even counting that lame-ass yawn-fest baseball.) there may come a time when the USA is up there with the best of them.
