It goes both ways. he kids taht are bigger at the younger ages tend to fizzle out quicker. Not just tall, but mature (shaving, etc.) Those are the ones that usually get passed up. But, some of them keep growing and end up studs. 13-14 is in most cases a bit too early...The kids that aren't as big but are more fundamentally sound and can play with the big boys usually end up being the studs when they grow.
