Flo Jo didn't either. The 400lb squat sets and setting the world record by half a second was pure coincidence.Did he just pull a Marion Jones? She claimed(& still does to this day) that she didn't know she took PEDs. Yes even though the evidence suggest otherwise( people witnessing her inject steroids in her legs, calender evidence given to her when to keep up her doping schedule, her husband testing positive for steroids).
I doubt anything will happen because the NCAA only goes after certain schools and ignores the obvious cheaters like Bama and UGA.
