Patrick Chan remembers just about everything from his Olympic debut eight years ago in Vancouver, including the controversy that erupted when Evan Lysacek won the gold medal.
Evgeni Plushenko of Russia landed quadruple jumps, the toughest in figure skating, in combination with a triple toe loop in both his short and long programs. But despite leading after the short program, Plushenko was beaten out by his American rival despite Lysacek never attempting a single quad.
Fast-forward to next month's Pyeongchang Olympics, and Chan is amazed at the transformation that has taken place in the sport. Salt Lake City native Nathan Chen is planning an audacious five quads in his free skate, and it could take at least three or four to have any shot at landing on the podium.
