I don't have a clue if he breaks a rule or not. Seems to me to be doing what Fulton was able to pull off for years. It was a genius move when he brought that OC in. Whether how he's pulling it off is against the rules or not, heck if I know. Only people that would have bona fide evidence probably don't want the TSSAA sniffing around Knox Co. at all so they keep their mouths shut.
I doubt my friend does either, but he's been in the same coaching circles. But when you are managed to not be liked or, in many cases, respected by nearly everyone in your profession for one reason or other, eventually it catches up to you.
