A kid who plays for his HS team has a huge advantage over a kid who just finished 8th grade (e.g. exposure to HS coaching, practice, games, competition, etc.) That's why the rule was established in the 1st place.
why stop there? I think kids over 5' 11" should not be allowed, and maybe have speed and agility testing and kids that are just too fast should also not be allowed, I would definitely not allow kids that shoot too hard, and no kid that goes to Chaminade would be allowed because if they went to a public school they would be on varsity. We need to balance the playing field and make this for players of the lowest common denominators - let's call it the Harrison Bergeron tournament of champions......or, another ides might be to allow any kid that was born after 9/1/1996 - just a thought.
