All of this kinda goes back to the myth that clubs/countries comprised of the biggest, fastest, strongest, most athletic dudes a nation (or checkbook) can offer, don't win as often in soccer, and how it relates to America's success/lack of success/future success internationally. Look at this Bayern team for example, very good athletes across the board. This seasons Real Madrid team is another example. They are crazy athletic. Ronaldo, Bale, Di Maria, Isco, Benzema, so much talent. I hadn't seen much of Isco until recently, but man, he is nasty.
historically, just look at brazil. they have great skill and a ton of big/fast/strong guys, too
