The gold already was assured. Shaun White could have played it safe. He didn't need to drop his new toy, his new trick, at the end of his second and final run.
He didn't need to throw his tired body into the air, rotate 3 ½ times, flip twice and land perfectly. He didn't need his Double McTwist 1260.
But playing it safe isn't in White's nature. And it's practically against the rules of the halfpipe.
