I have to totally disagree with you. With that said, there are always some exceptions. I'm not sure what you mean by "high level AAU". You can get away with "some brief circuit stuff your junior year" if you are exceptionally talented and seen by the college coaches while you're on the "brief circuit". It's not like they go to every high school game looking for players. They go in April and July, then determine what high schools to scout based on what they saw in the spring and summer.
It's up to a parent to put together the best plan for their child. There are a number of ways to approach it to make sure the kid is having fun, playing competitively, receiving fundamental skill training and maintaining academic excellence.
