15. Michael Phelps
Although he’s the most decorated Olympian of all time, Michael Phelps has been no stranger to controversy. Specifically, the swimmer – who has won no fewer than 23 golds for the U.S. – faced a six-month suspension in 2014 when he was charged with drunk driving. Nevertheless, Phelps still bagged five golds at the 2016 Olympics and has since retired with his reputation seemingly intact.
14. George Foreman
George Foreman is best known for his Rumble in the Jungle against Muhammad Ali, but he’s also an Olympic medalist. In fact, the boxer brought home the Heavyweight gold medal for the U.S. in the 1968 Olympic Games. And after his success in the ring, Foreman endorsed his own Lean Mean Grilling Machine, which has now sold over 100 million units worldwide.
