I have to give you credit. You used this same argument in opposing girls DA, so at least you are consistent.
I'll just say this. In the youth game it is relatively easy to score as a superior athlete. You just dribble or run past the slower defender and knock the ball in against a defenseless keeper. It takes training to learn how to beat a competent defense - e.g., how to make your runs and how to get a shot off with a defender or two in your face.
... And it requires even more training to know when it's a better idea to dish to off to the wide open player on the flank.
