I am going to agree with you. Actually college soccer is mostly composed of American, along with some foreigners. If you are a young player thats good overseas, there are alot more options than playing for a college team in the US.
What better opportunity for a foreign player than to study at an American university? Most will not make the big league clubs in-country, but they could probably get a partial scholarship to play at many US D2, D3 schoools. Just a thought.
