The problem with US is that they don't have enough experience playing against European nations and south americans, such as, brazil and argentina. Most of the countries that US has to face in World Cup Qualifications are pretty weak ones. Also, the US expects a lot because of it ridiculously over-rated FIFA ranking. I think they didn't deserve to go to the next round and the result was fair. They might wanna play more games with good countries instead of just boasting about their artificial ranking to everyone.
