I understand playing defense under the basket is not really playing defense, hence the arc in college basketball. But until it is implemented in high school, it is still LEGAL to set up under the basket, so coaches teach it to draw charges.
It has been suggested for the last couple of years and has gotten more votes each year, maybe it will be this coming years change or even the year after, but it is coming soon, until then, kids will continue to do it and it will continue to be taught until its changed. As an official, you can not just not call it because you think it should be, you have to call it by the book rule and it says its still legal.
