OK. I understand about the Villanova camp (Next Level), and that some DMV camps may not really be good. However, are there any camps that officials specifically use to prepare themselves to go to the G-League tryout camp?
AFAIK, the G-League camp uses NBA rules and mechanics, and you have to learn those rules and mechanics somewhere. However, most of the camps mentioned in this thread are tailored to high school and (aspiring) college officials. Are there any specifically dedicated to teaching professional rules and mechanics?
