No offense to Shizuka, she was the best thing about the 06 Olympics but she was lucky to win that one much less another one. She did a great job at the Olympics but she didn't exactly put her name in the books like some of the other ladies.
Had Sasha not fallen twice in her LP at the 06 Olympics, she would have been Olympic champion instead of Shizuka. She led after the SP and she had a better LP than Shizuka. Sasha was also 21 at that point and very much at her peak as a skater. When one looks back on her career, that was her big opportunity and it was a big opportunity missed - not 2010. Even if she had made the 2010 Olympics, there was little likelihood of her winning given the form Kim and Mao were in.
