Thank you everyone. This is really helpful. Agree that it makes sense for him not to wait and reach out.
To answer the questions he did let all the coaches know ahead of time that he was going to be at HF when he sent them his summer schedule (along with his summer video), so not right before the camp. A number of coaches at that point let him know they were interested in seeing him play and would be at HF.
To Branson's question, he wasn't actively seeking coaches at at camp which I know is a mistake, it's the main thing they tell the kids to do, but that's just not my kid to be comfortable with that part of the process when the coaches are getting hit up constantly. I'm sure this didn't help him. Hopefully it didn't hurt.
