What does American swimming icon Katie Ledecky have left to prove? Not much.
Her medal record is eye-popping: seven Olympics golds and three Olympic silvers to go with 21 world golds and five silvers. She owns the world long- and short-course records in the 800-meter freestyle and 1500-meter freestyle. No conversation attempting to rank the greatest North American athletes of the 21st century is complete without her.
And yet, not only is Ledecky primed for another big Olympics this summer in Paris, she also indicated to NBC recently that she might not be done after that.
