The major sports in the U.S. have become a melting pot of nationalities. No matter the sport, you'll now find players from nations around the world participating.

So why do they still conduct events like the Ryder Cup (right now the U.S. vs. Europe) and host hockey All-Star games with the U.S. vs. the world? Don't the Olympics cover the arena enough, where one country can say they are "better" than the other? And actually, now that athletes can pretty much participate with whatever country they want, even that's not a true testament to a country's athletic prowess.   

I think the time of one country trying to say it's the best in the world at any sport is ridiculous in this day and age, and this contrived competitions are done simply for ratings.

So why don't they have U.S. vs. Japan in hot dog-eating contests? Or make the American Gladiator series a country vs. country spectacle? Bowling anyone?

Perhaps someone can explain this to me.
