Can you imagine how good the USA mens soccer team would be if soccer was the number one sport in the U.S.?

Give it 10 years, China will be at the top .

They do have potential, I don't deny it, but I've always thought the USA are a much bigger sleeping giant in rugby union than soccer.

Sure they'd be much better, but that alone wouldn't fix the issue of all the excellent youth players who are overlooked because they don't have the income or connections to develop from a young age. 

Talk is cheap. Can you imagine how good Russia would be if those big bad Russians played American football? They would dominate the NFL. Right?

They would have won 1 by now but i doubt they'd dominate. Part of this is the American attitude. For some reason the English speaking countries never learn from others. England stuck to 4-4-2 for a long time when the rest of the world had moved on. America to be the best consistently would have to learn from other countries. You need to evolve and adapt. I think much like England tried to stick to the english way and have won nothing since 66, i fear the Americans would constantly try to do it the American way...

Edit - U Bin Called, in football the top players still play international football. Unlike basketball, winning a world cup is arguably the biggest prize in the sport.

Still rubbish, americans are too fat and lazy 

I'd guess we'd do as well internationally as our National Basketball Team does now.

The question, of course, would be if our National Team would attract the best players as it does in other proud nations.  If soccer really were the "Number 1" sport in the USA, would there be so much money involved that the top players might pass on international play to preserve their lucrative pro careers?
