I just read the SI article about this story today. It seems a whole group Bama of players met with the snake oil salesman in a hotel room on the eve of one of the big games and not only used the substance but were given the product free of charge... (tattoos and bling anyone?). The salesman taped the interaction and said they could have it for free but if push came to shove they were to say they bought it from him and he would back them.
Now... the NCAA will probably never investigate this but instead Tricky Nicky Saban will likely self disclose the offense, the unimportant players will get bounced, Bama will promise tighter institutional control, and the NCAA will sent a sternly worded letter telling Bama not to do it again.
The NCAA is not going to do anything to hurt Bama, the SEC, or ESPN, as we all know... you DO NOT KICK THE GIFT HORSE IN THE MOUTH!
