I really don't know if there is a more demanding sport when it comes to conditioning. Except for the goalie, who doesn't have to run much, the others are running all the time. I admit that I don't know all the rules of the game, but I really enjoyed watching it during the Olympics, both men's and women's soccer.
Oh yeah, and the USA beat Mexico last night for the first time ever. How many of those line drives can you take off your head before that becomes a problem?
