I totally agree, I am from a small town in middle tennessee, we dont have many gyms here but my high school coach was just a call away from unlocking the gym anytime, for any player that wanted to work on their game, I believe he understood the same principles that you do but also it is somewhat a lack of kids being motivated or even interested in fundamentals, i mean it is the little things that go the longest way. I went to school with some star athletes but most never made it in college due to their lack of preparation in high school and thats not the coaches fault...you can bring the horse to water, but you can't make him drink it.....
