I just gotta add . . . as a former soccer-hating American (the soccer-hating part, not the American part), and as is true about us yanks a lot of times about a lot of things . . . it's amazing how much your perception of a subject will change when you confront your own ignorance about it and actually learn something.
Additionally, having played basketball, baseball, hockey, and most recently in my life -- after learning to love it -- soccer, I find soccer to easily be the most physically demanding of the four.
ETA: And Hope Solo is hot but don't forget Heather Mitts! She's pretty much a ten.
