I understand your point and in highschool that is probably true. But in the DA it is not. Koty Millard is no where near 6' tall and he is on the national team. Joe Amon, Devin Lameroux, and Rex Epps are all the same. None of them are over 6" tall or weigh over 165 lbs but they are all extremely effective for their teams. Your right, Messi is the best player in the world. If he came and played against the U-16 Academy players he would probably perform decently....
