The United States plays crappy soccer? Correct me if I'm wrong, but our national team advanced to the round of 8 while seven teams on that list (France, Italy, Argentina, Czech Republic, Portugal, Holland and Ireland) did not back in the 2002 World Cup.
I'm not dumb enough to think they're the best in the world, but I'm just trying to contradict an earlier suggestion.
As to who is the best, though, I think I'm gonna throw my hat into the ring and say Brazil. Those boys always seem to be on the world scene, and it's hard to argue with "defending World Cup champions".
