I would start playing soccer in a local league and follow more soccer in general.
I'd also buy my first ever soccer jersey of an American player! Gee wiz.
What about you? What would you do if the USA were world champs?
Are you even watching the World Cup? You better be. Grr.
Why do you have to wait till USA wins the World cup to do any of that?
Shouldnt you do it if you really care or liked the US Football team and or Football in general?
Are you really that big of a douchebag hipster asswhole dick face ass hat that you would only care about football only if the USA wins?
on topic: like so many before me I would do nothing. I was just talking to my brother earlier about flopball and the worst part about the sport is that it's not even interesting when the US is playing. Normally I can suffer through sports I don't like (hockey, baseball) if the team I like is playing (coyotes, diamondbacks) and both those teams are not good (the diamondbacks are actually more like terrible this year...so far)
Nothing as despite what the media would have you believe for the last 40 years, soccer will never be very popular in the States and very few people will care if we were to impossibly win the whole kit and kaboodle other than utter a minor..."oh, that's nice".
