For sure. Since then, however, I think that the will for oversight and the stigma associated with offending have increased enough to make it comparatively uncommon.
Of course the stigma isn't absolute, nor is the oversight perfect. But I don't think those balances had to tip 100% to sufficiently deter players.
Obviously none of us are insiders with locker room phlebotomy kits and spreadsheets of real data, so this is just an educated guess. Still, I'm betting compliance is the norm and that there is a healthy chunk of P5 programs that truly are 100% clean.
I wish I were equally trusting of their schoolwork and refusal of impermissible benefits.
