Ernie died a few years ago, but no...many players just want to play adn continue to do what they do and many coaches are busy trying to put players together and nto teaching the fundamentals maybe as much as they should. Just because a person coaches high school doesn't mean they teach shooting...
I want to be careful how I say this, because I don't want this to come off as pure criticism.
Prefacing my comments: Yes, there are some wonderful youth coaches in all sports, at all age levels, club/travel, organized, HS, etc.
With that said, my experience has been that there are very few true "coaches" at the high school level. I can't speak to historical comparisons, but there are all to many HS coaches with the "bring me your game" attitude/approach. It seems there's very little "investment" and development. TRUE development. And I'm not talking about HS coaches who have a summer camp. Or those who take a "select" team (younger ages) and play in tournaments in the offseason. I'm talking TRUE development.
By the way, my "bring me your game" comment was an actual quote from an actual (former) High School head coach. That was this person's attitude: "bring me your game."
What a disappointment.
That person had moderate success when the truly talented classes arrived, but had no ability to develop individuals nor a TEAM.
To be fair, some do exist. Not enough.
