I am sick of hearing about exposure as a selling point to get kids into club ball and paying $200-$400 dollars to get on these teams. I agree that it is beneficial to kids but not to all kids. I personally feel that club ball all summer for a kid that needs to improve in various areas is not a good thing. That is the case for lots of kids, for example : take a kid that is 6'3 playing on a team with not much size. this kid is most likely going to be playing the 3 or maybe the 4 spot. He is not in a position to handle the ball much therefore he won't get the opportunity to improve in an area that will prepare him for the next level. In club ball, as oppose to the park or open gym ,you will not work on such weaknesses like dribbling or left hand lay-ups or outside jumpshots if these are weaknesses. You will stay in your comfort zones while playing in these games, which means that you won't improve in these areas. There aren't many club teams that teach you how to play and work on your weakness, they take what you already have and use it accordingly.
Exposure is great when you are ready for it. If not , do summer training sessions, open gym basketball , park basketball and focus on weaknesses. A tournament or two during the summer is good enough when you clearly need to work on your games , DON'T DO CLUB BALL ALL SUMMER. It's not helping you get better at the things that you need to focus on. What are you exposing?
