lhp mom, I can relate completely to what you are saying. I know there's alot of jealousy in any sport including baseball. My son has a teammate that will be drafted high and probably be Mr. Baseball in our state. I have had several people come up to me and say "he doesn't look all that impressive to me", "what's the big deal about him". Just like you, I say "93-94 mph". The kid is a great kid and obviously has a great future ahead of him. I truly do not understand when other baseball folks can't share in the joy of their son's teammates, other kids they know, or the sons of posters on the HSBBW. I love baseball and am genuinely happy for every kid that succeeds and enjoys the game at every level.
By enjoying and celebrating other people's success doesn't lessen your son's accomplishments. It lets him join the party and learn that life isn't always about "you". Sometimes, parents forget this lesson.
