I don't understand this train of thought whatsoever.
It's not the cheating that has Pearl's job in question.
It's how he handled the situation. If you tamper with an NCAA investigation, that should lead to an immediate termination.
You get caught, fess up. It was a minor violation.
You lie and lie and continue to make a fool of yourself, then come out crying, well there's no sympathy for you. Now you've turned a minor slap on the wrist into a full blown NCAA investigation because you're too stupid and/or scared to admit you cheated.
Every coach spends time in the "gray areas" of recruiting.
The majority are able to self report secondary non-sense and keep it from blowing out of proportion.
