A week ago we were all worried that she wouldn't even show up, or that if she did poorly in the competition, she'd petition her way onto the Olympic team. Instead, she arrived, she stuck it out, she skated a grand short program, and she managed pretty well in the long, considering her short training time and lack of competition experience in the past few years. Then when she didn't place as high as she would have wanted, she took it like a champ and graciously left the spotlight to the winners. I suppose this can be called a "failed attempt," but it's by no means a failure. As for whether it will "taint" her career, baloney! Go look at her best performances on YouTube and see whether she suddenly has bad posture or a lower spiral in any of them. No? I didn't think so.
Should she have stayed away? Not if this was what she had her heart set on. She was entitled to show up, she didn't take anyone else's place away, and she didn't let anyone down with her attempt--least of all herself.
