His falls are terrible and it takes him so long to get up - then at the end of programs he looks like he can't breathe at all is going to collapse. I do not enjoy his skating at all because it doesn't look like he can handle skating physically. I don't really think of posture.
He's stamina has gotten better a little bit from the past though. Last season at 4CC near the end of his program he popped a few jumps and this year he at least landed all of them at the end of his program so there is some little improvement. He does take a while to get back into his program when he falls, CoR and CoC, but at worlds he was injured so maybe that might have affected his slowness to get up even more. It's been said he has asthma, but I wonder what is the main trigger for his attacks. It would suck if it was exercise.
