To the OP, you are not off base. It is annoying. However, parents of 9U to 11U athletes are the craziest among all of the parents I have ever dealt with. Add to that the parent of a pitcher, and you have to take everything with a grain of salt. Most of what a parent tells me about their kid goes in my left ear and out my right ear. What I see is how I determine how good a player is. Everything else is fluff. If they don't ask for my opinion, I don't offer it, and it is best just to smile and encourage the kid to keep practicing. Don't let the parents get to you.
