Saying soccer will never be big here assumes American culture is static. USA could wind up starting our own brand of soccer here to account for some of the game's issues. How about soccer with no goalies? Now that would be something!
PS I watched Major League Soccer and FIFA on Fox Soccer Channel for 10 minute sessions last year. I spent 20x as much playing Winning Eleven Soccer on PS2 with Randy however. I believe I was slightly dominant, and it ended in sudden death. It was at this time we both believed that Winning Eleven was popular, because choosing plays in Madden backfired.
