Honestly, I have noticed the better the kid is, the less the parents talk. A couple of kids my son went to HS with wound up drafted out of college. One is playing in MiLB, the other was drafted twice, but declined and will be playing his senior year at Kentucky. The first guy was drafted out of Clemson. In HS, his parents NEVER talked about him. Even when prompted. I would ask them questions in talking to them and they were very reluctant to talk about any accolades or stats or anything else. The other I still talk to his dad about baseball and we follow his son's games together, but never a bragging word or saying much to bolster his kid up at all.
Like I said, the better the player, the less the parents tend to talk.
