Lindsey Vonn just wanted to win. Win every time she put on skis. Win more than any other female ski racer before her. Win no matter how much she hurt or how much the eventual cost would be to her body. That might be why Vonn was so perplexed the other day when heir apparent Mikaela Shiffrin — who grew up wanting to be another Vonn and may one day surpass her as the greatest female skier ever — decided against trying to win five medals at the world championships in Sweden.
