Its interesting that people say that many american footballers would likely play in other sports professionally or Olympic sports if it were not for the fact that they play American Football. How much of that is actually true and how much of that is just people playing up the quality of American Footballers? I know in the case of Soccer players what makes them good at soccer is often not their athletic ability but more of a natural talent at that particular sport. No doubt they would be great at a variety of other sports but they wouldn't be able to compete at a competitive level. In the same way, Rafa Nadal is incredibly athletic and I bet as a kid he was great at all sports but his talent lay in tennis and that is what allows him to be so successful at a particular sport.
If the rest of the world invested the time and money into American Football there is no doubt that the US would face serious challenges by other teams and the reverse is true with Soccer. If the US invested more money and time in Soccer there is no doubt it would also give the rest of the world a real challenge. Who knows how many Maradona's, Zidane's and Messi's the US may have produced otherwise.
