Seriously, I have done the same things you have done. I have looked at my son's stats and wondered why someone with lessor stats was considered a better player. Now that he is in the minor leagues, it is easier to do and yep, I still do it. We try to use it as fuel for the fire but I'll be honest, it gets old eating humble pie all the time.
I truly believe you'll be better off if you let others notice your son on their own. I see no reason to force-feed anyone. Your son's baseball abilities speak for themselves.
Sorry to hear about your son's diabetes by the way.
