Sports stars are one part celebrity, one part athlete. Like so many celebrities, some sports stars are prone to scandal. These sports stars are were involved some of the biggest controversiesof all time, and many remain controversial figures to this day despite being retired. O.J Simpson is perhaps the biggest controversial athlete of all time, for “not killing his ex-wife” in 1994. Remember when one of the best NBA players of all time, LeBron James, took his talents to South Beach? That was definitely a case of a sports star who caused controversy. And then, of course, there’s Anna Kournikova, who has caused controversy simply for being beautiful. Which athletes do you think are the most controversial of all time? What is your definition of controversy? Is it off-the-field antics like the domestic drama surrounding Tiger Woods, or is it on-the-court antics like John McEnroe’s famous profane meltdowns?
