That's the problem. European kids aren't playing for competitive purposes, they're playing for development. Winning your U10 league shouldn't matter. Learning how to control a pass should be the focus. Guys like Eddie Johnson go flying through the youth ranks without any technical ability because they can physically dominate in their age group, then when things like touch and creativity matter, they're useless.
I agree with your assessment on where the best athletes are going. That's why we need to develop soccer brains, not just guys who can run past their opponent because speed is relative to who you are running against, but knowing how to get yourself into space to get a shot off is a skill that works at any time against an opponent. Speed is also irrelevant if you don't have the touch on the ball to put it in space for you to get up to top speed and go by your defender. Also, I'd say that in terms of straight athletics, the US National Team is as good as or better than any in speed, strength, and size, but we're lacking in vision and touch.
