If you're playing at LakePoint there's a good chance there will be hundreds spread across the complex, (from just about EVERY conference in the country) at every part of the day... Depending on the depth of talent of the teams playing could determine how many coaches are at each particular game. Hopefully the organization you're going with has a reputation of getting kids committed, because that could possibly outweigh depth of overall team talent... Coaches do travel to the High Schools around the Atlanta area during this tournament if they're interested in players...
Good luck!
