Do you think I could go to the clinic even though I have no basketball skills or athletic ability whatsoever?
I guarantee that you won't be the only one, and that they aren't going to ask who/where you coach when you send in your check.
This is about money & making contacts. Just send in your check if you want to go, the only time people will ask where you coach is when you're sitting around eating and bs'n, just tell people you coach your daughter's aau team or something and no one will pay any attn to you.
