I am sure that if what PG says is true, you need not worry much. All good things will come and I think that you have made a good plan for your son to be seen by the schools he is interested in.
Fungo,
My son didn't receive half the letters that most people think he did! I remember that some came after Jupiter, after coaches had seen him play. And he did have some offers without ever having gotten a letter or questionaire, one certain school being in Alabama. Of course didn't hurt that one of his coaches had a son that played on that team.
Point is folks, answer the questionaires, answer as many as you wish, but unless you are out and about somewhere being seen, showcase, tournament, camp, having a coach who is willing to help because he knows someone, it doesn't mean much. Don't let the amount of mail you get now be overwhelming or disappointing. JMO.
