The recent past isn’t filled with “good guys,” as it were: the early 2000s ensnared many of America’s biggest names in the sport, including Marion Jones, a star at the 2000 Olympics in Sydney, who admitted to using steroids and was stripped of her medals. Tim Montgomery’s 100-m world record, set in 2002, was stripped. And the current team in Rio includes athletes who’ve been suspended for doping. Justin Gatlin , America’s fastest man at the 2016 Olympics, tested positive for performance-enhancing drug use in 2006, and served a four-year ban. Tyson Gay, a member of the . 4 X 100 relay roster in Rio, tested positive for an anabolic steroid in 2013, costing the entire . 4 X 100 relay team at the London Olympics their silver medals.
