Smitty, that is exactly the case with my son.
Mine too, but i cannot use location as a reason as we are in Atlanta, i really thought he had the stuff to get a deal based on his sophmore year/summer, college interest then and workout regimen/focus. I think about that $700 and the 3-4 invites ($2800 + expenses saved) we finally starting getting from PG after he was on the "map" with colleges and now use that money for a scooter for getting around campus, new set of golf clubs and whatever else he needs while over there in Clemson.
My son does have a rating but it was from the only showcase that he attended. That is why I mentioned, in our situation, that it is only showcases that have ratings. The other 7 PG events he has attended did not have ratings.
This is the answer. If you look at the events, you'll see that almost all of the guys with no rating have not attended a showcase. Many players attend numerous tournaments without attending a showcase and, therefore get no rating.
