Dibble, while you are right that getting a 1,000 calls would be annoying, the reality is very few parents and especially students are actually picking up the phone and calling coaches. I have met coaches that are simply begging for kids to call them because no one ever calls anymore, because they are afraid or don't know what to say.
Simply call the coach, tell them who you are, where you are, what you do, and that you are "possibly" interested in their program.
The coach will simply ask your grades, what positions you play, what tournaments, teams, showcases you will be playing in and then you can go from there, nothing more, nothing less.
You dont have to call up and say you are the next Roger Clemens. The phone call is simply to introduce yourself and get the ball rolling to the step in the process.
