Historically, the problem has been that the some of the "privates" have not maintained the existing rules. Clearly, the number one rule that keeps tripping up the "privates" is recruiting. Yes, it is not every "private," and there are plenty of "public" schools that bend and break rules as well. It would not matter what association the "privates" were in -- if private schools keeps bending and breaking the rules. Why don't the headmasters stop the nonsense of recruiting?
Seriously, who wants recruiting in Tennessee high school sports? Please show me a tuba player than any high school in Tennessee has recruited! The insane desire to win has corrupted high school sports across the land, not just in Tennessee.
