Actually, gdf, the best camps are those with the most college coaches present. Sounds simple, but it's true. Blue Chip and Five Star are pretty popular, as are individual college camps such as those conducted by coaching staffs at Georgetown and Transy. Whenever you hear of (or are invited to) a camp, make sure you find out how many college coaches will be in attendance. If the organizers say "50 have been invited," that's not good enough. Find out how many attended last year - and get the list of schools. If they don't want to provide that info, don't attend.
Good AAU tournaments can be just as impactful. Bottom line, you have to get your name out there, and preferably your ability. Most college coaches attend camps, showcases and tournaments specifically looking for someone whom they have already heard of.
