This is my observation as well. I have a boy and a girl.
Boys' parents lose hope early in the process. My son's teammate was accepted into an MLS academy and the dad told me that he is relieved because he is quite sure that his son will finally realize that becoming pro is not realistic. He knows his son is not good enough but it is hard to convince the son if he is a star player on an ECNL team.
Girls, on the other hand, I know personally a handful of parents that have been so angry at coaches, club DOCs, even walking up to high school principals claiming discrimination for not starting a game. They should know that if you have to fight to get regular starts at an ECNL or high schools teams then it is hopeless, just enjoy the game. maybe even join an ECRL team to be the star player.
To be fair, it is difficult to differentiate the "elite" unless you are physically elite like Rodman, Morgan...
