So what? For 99.99% of players, high school is the end of the line. Maybe 100 players get invites to a any national camp each year, and even less actually make a team. This includes everyone playing ECNL or GDA. You aren't going to make the national team. You just aren't. Giving up the high school experience so you can "develop" is absurd. There may be other good reasons to give it up, but it is crazy to give up one of the funnest and most rewarding experiences of your soccer career just because US Soccer thinks something that is demonstrably false. By high school, for basically everyone, the development game is over. You might, maybe, possibly go on to play for your colleges (anyone want to bet how many of those players didn't play in high school). Holding out for the additional development (and it is completely unproved that development is what you will get), is crazy. You only live once. Live it well.
