How do you emphasize a rule that doesn't exist?

I don't think its as complicated as some are making it. The rules say players may enter the "lane" on release. The semi-circle is NOT part of the lane. The POE is clarifying that when NFHS changed the rule they did not intend for players other than the shooter be in this space.

If the defender steps into the semi-circle I will call the violation, the first time and every time (assuming a missed shot of course). It is not that difficult to block out without crossing that line so they will have to adjust to how it is being called or continue to get violations.

As for contact, I called several fouls this last year when defenders displaced the free throw shooter. Coaches never liked it but if you move ANY player backwards out of their position during rebounding action it is by definition a foul.
