Impossible to measure? Huh? How do you figure? You just love to make up stuff don't you. You don't think athletic ability can be measured? LMAO. ] America doesn't suck at it. It's that we have better alternatives here. Why be a nurse when you can be a doctor? Why be a fry cook when you can own your own foodstand? You just like blaming Pat McEnroe for US tennis inevitable downfall. Tennis is less popular then it used to be at the rec level AND we don't get the best athletes going into it. It's no wonder that our tennis is slipping. Likewise I don't blame the US leader of squash for our woeful squash program. Few people play squash in america. It's a great game. But if you don't have alot of people playing and don't get the best athletes your sport is going to be weak. it happens to any niche sport.
