Olympic champion Mark Spitz holds up an issue of Sports Illustrated with Michael Phelps on the cover. Phelps won eight gold medals at the 2008 Beijing Games, breaking Spitz's 36-year-old record for golds in a single Olympics.
"It goes to show you that not only is this guy the greatest swimmer of all time and the greatest Olympian of all time, he's maybe the greatest athlete of all time," Spitz said. "He's the greatest racer who ever walked the planet."
