22. Ben Johnson
Johnson went from hero to villain overnight in Canada. He became an icon after winning gold in Seoul in 1987. Unfortunately, it was too good to be true. The sprinter failed drug tests after the race and lost his medals as a result. A glance at his bulging physique before showed veins popping out of him – it would have been crazier if he wasn’t on steroids.
Crazily, Johnson failed several more drug tests after this. He attempted numerous comebacks but never stayed clean. After his third failure, a Sports Minister branded him a national disgrace. It’s safe to say that he lost all credibility because of this. Few people had any respect for him because he was a blatant cheater. The reason he’s not further up this list of shadiest sportspeople is that he was too dumb.
