our kids play too many games. By the time they get to college/pros they have played so many more games than a European player has and put that wear and tear on their body.
The flip side is that our guys don't get coached up enough. AAU teams generally just play and play and play and play. Rarely do they sit down and work on skills with the kids that will help them improve in a practice setting. As such, a lot of AAU games become more like And1 commercials than organized basketball.
