The question hovers over Shaun White — not so much the way a black cloud might linger but more like a whiff of smoke he casually can bat away. What if he's not good enough? Instead of avoiding those sort of conundrums, the world's best snowboarder pursues them. —On the halfpipe, where he spent the better part of a year trying a trick he couldn't master but nonetheless emerged a favorite for a third straight Olympic gold. —On the slopestyle course, where he eagerly took up the challenge presented by the Olympic overlords, who gave him a chance to win not one, but two, gold medals in Sochi. —Even on the concert stage — with a guitar in his hand — where White and his band will soon tour the country to promote their newly released album.
