If you have ever played AAU and been invited to a phenom camp, you will play as high as 8 games in one day. They sub alot , but never the less it is an all day thing. It builds indurance. This is middle school kids. They put you on a team with kids you don't know and that is a challenge in it's self. So if you are going to play the teams from Lexington and Louisville, that is what they do. If you want to keep up, the more you play the better you should be. I have heard that SL played AAU from the time they were grade school kids. Not sure about that, but it makes sence. They have camps that last as long as 3 days.
