I think you're romanticizing things if you think any program that aimed to be competitive didn't have systematic cheating occuring pre-NIL. I don't think it had anything to do with who the coach was or wasn't. The infrastructure for being a competitive program is larger than a coach.
A coach could either choose to be more compliant with the infrastructure or turn more of a blind eye to it, but at a large program they had no power to stop it.
