E ight years of waiting came down to one hundred seconds on a sun-splashed, near-windless Wednesday morning in the Taebaek mountains. But the greatest skier the United States has ever produced was left with nothing even resembling a regret with the end of her Olympic career now within touching distance. Vonn made no major errors but still finished 0. Only an improbable effort from the Norwegian outsider Ragnhild Mowinckel nudged Vonn down to third, but still the history continues to topple down around her. That injury, a torn ACL and MCL with a tibial fracture whose reinjury later that year cost her the Olympics, was followed by a fractured right humerus less than 21 months ago that left her unable to brush her teeth.
