the "stars" rarely turn out to be high school players. Then dominate ll because they grew faster, etc. so they never bother to listen to the coaches on technique.
It's your middle of the bench players who turn out to be really good, if they grow physically. Because they listen to the technique.
And sometimes the end of the bench kids will get that growth spurt and become dominate.
But if your area is like my area, you need to be playing travel ball to have any chance of making a high school team.
