With Mao crying for an hour over missing a jump in the SP, and fans saying she needs to change coaches, I just feel this needs a bit of discussion.
To me, if a skater consistently misses an element, then I might blame the coach. But I always feel that it's the skater who actually misses an element. It's the skater who is on the ice - not the coach. I'm sure Mao won't make a habit of missing that jump regardless of what coach she is using.
