He totally deserved to win, but it was far from his best skate. I have a feeling Yuzuru's best is still to come, considering he didn't even try his loop or lutz here.
I think he was more like go or die. He thought he must do 4 quads to be competitive against the other men and who could blame him?It wasn't his best, but it likely would have been equal to his original best showings of Seimei if he had just kept the 2nd 3Axel instead of trying to throw in a 2nd 4Toe.
Yomiuri newspaper reported this morning that he started jumping quad 10 days before the competition, but it didn't mean that he was fully healed and he had to take potent medicine to calm down his pain. I was very shocked reading this but I didn't post it here because I thought it was better not to since it was just right before FS and we needed to be positive and supportive for him. And I also thought we'll get more information later from Yuzuru directly.
