If you asked MMA fans a year ago who’s the greatest MMA fighter of all time the name Anderson Silva would most likely pop up alongside that of Fedor Emelianenko and Georges St-Pierre. However, this past January, Silva failed drug tests after his fight with Nick Diaz and the worst part is that he kept lying about it until the second sample verified the illegal substances in his blood. Ironically, Silva was one of those athletes who kept criticizing cheaters and people who use steroids while doing exactly what he was preaching against. His legacy was greatly damaged and he was banned for one year.
