For me - I think that he knowingly took a supplement to gain muscle mass. I also think that he knew (or should have known) that this supplement was not permitted. UF gives out supplements to athletes. Grier chose to go his own route. So I think that he did something that he knew was wrong and would get him suspended if caught. He rolled the dice and lost.I've read where some say "I don't believe him (Grier)". What exactly did he say that would make anyone discredit what he said. The video is out there and his comments are public. Coach Mac said "he made an honest mistake", but Grier apologized for taking a banned substance and said he didn't check with the medical staff. He never said "I didn't know what I was taking". Is it that he was disingenuous in his apology? It's been said that he volunteered to come forward to address the media and that no one asked him to do that. Just curious what was dishonest.
Just my opinion, but it is based on everything that I have read about this.
