Every young sports fan dreams of being a professional athlete - the fame, the fortune, the adoring fans. But when it comes to these athletes, all bets are off. Legal trouble, PR trouble, you name it. In the wake of former cycling champ Lance Armstrong admitting to doping in an interview with Oprah Winfrey, here are more stories of athletes' most dramatic falls from grace.

Live ... strong? Lance Armstrong was a hero, a fighter and an icon. He beat cancer and amazed us by winning title after title at the Tour de France. In June 2012, he was accused of doping and stripped of all his wins (how many total?). He even lost his endorsement deal with Nike (what else happened?) - and Nike doesn't drop anyone (Tiger Woods still has his deal, and they even brought Michael Vick back on).

Despite denying that he raped Desiree Washington (get details on the case), Mike Tyson served three years in prison after he was convicted. He never regained the "Iron Mike" persona that made him boxing's most feared fighter, eventually becoming a sideshow after partially biting off Evander Holyfield's ear during their famous bout (watch a clip).

Despite O.J. Simpson's famous acquittal in 1995 of double murder (who were the victims?), the Hall of Fame running back became a pariah. Most Americans believed he got away with murder, and he lost the subsequent civil suit (how much was he ordered to pay?), confirming public suspicions. His promising acting career ended abruptly. His endorsement deals disappeared. He tried to cash in on his notoriety with a TV reality show, "Juiced With O.J. Simpson." It flopped. He wrote a book, "If I Did It," which read like an admission of guilt.
