As an athlete mentor at the London Olympics, Louganis is trying to make sure the stress of winning medals isn't heaped on the shoulders of American divers, who have been chasing his standard of excellence since he became the sport's icon in the 1980s. The U.S. has been blanked in diving in two consecutive Olympics, and hasn't won a gold since 2000. (AP Photo/Elaine Thompson, File)
