The coaches are not the biggest problem in this process. The problem is that every school has at least one message board, and most message boards have a writer assigned to know everything about the kid.
True Story here: I recieved a tweet from a college coach about my kid's game last spring. "Thats a nice swing, cant wait to get the lefty on campus #HRderby"
For 3 days I recieved over 40 messages from college coaches and message board columnists asking about my kid, wanting to talk to him.
My kid just turned 5. And it was a TBall game (but my kid did hit one over the fence, and one off the fence) The college coach is a high school friend. It is crazy.
(I put the kid on the phone to one of the writers. It was most excellent)
