The US produces a brand of athlete completely different from the rest of the world, you will find them nowhere else. Put it this way, there are people in the NFL as fast or faster than Theo Walcott, and they outweigh him by 60-90lbs. The issue is they don't play soccer, so of course we haven't had a single world class player, all the world class athletes we have are here -
NFL.com - Official Site of the National Football League
NBA.com
You can keep saying Soccer isn't reliant on athleticism,
yet Ronaldo is one of the best athletes in the sport and Messi is agile & quick as hell. Just so you know, the ability to change directions like that is.....athleticism.
Im not saying we'd dominate, but if the NFL/NBA vanished tonight, within 20 years the US would be a big problem in Soccer.
