School choice is an academically motivated animal and athletics play no part. Parents with students in horrible school systems don't want their kids to have to participate in said system and want a way out without having to get approved for a 300k loan for a smaller house and higher interest.
Will schools and parents take advantage of the rules for athletic reasons? I'm sure...some kids don't stand a chance academically and their God-given athletic abilities is their only way out of their situation...they'll definitely want to go somewhere they can be seen.

@amaidendevil said, at a macro-level view, this will force schools to get their ducks in a row both in the classroom and on the field...or be left behind.
Whether people agree or disagree, it looks like it's happening either way...you can get ahead of it and take it in stride ahead of other schools, or you can muck around, head down, for a few years and start in a hole that takes 15 years to get out of.
