Then by all means go play in a tournament that covers 40 miles with almost 200 teams! That ought to take care of his exposure!
On a serious note, the PG junior tournament held at East Cobb is amazing! Been there, done that. Won that. Hope to do it again! The WWBA tournaments are well-run and the competition is great. My point is that you can't make a great decision on a team based on ONE tournament. That's foolish.
You should have a plan that targets what schools your son is interested in attending. Go to the PG East showcase and write every school that he is interested in that he will be attending that. You should get more interest if you are pro-active.
My point is this- You are putting your eggs in one basket and that is foolish. He should play on an outstanding summer team and do a camp or showcase that targets certain schools if those events don't interfere with his team schedule.
