I too find it odd that PG Stats came up in a conversation. Did you, as a dad, go up to make sure that this ignorant coach knew how good your son was? Did your son go up and say to the coach that he had a great summer and the number prove that he is better than the rest of the guys? Personally, I love for my hitters to hit with wood as much as they can but in a game, no way. There are advantages to the wood in that, imo, they can make the swing mechanics better. There are advantages to these other bats and those advantages outweigh the wood bat in HS games. This is an interesting thread!
Finally, any negative conversations with you son about how you dislike this coach will not help your son. In fact, they just might be a reason why he isn't getting that shot at V that you want.
