So now we've moved onto the
Blame Yuzuru phase of this discussion.

Oh the drama!

Unless we have actual evidence to the contrary, can we please just go with what is apparent here?
The JSF has a long documented history of making arbitrary and sometimes, counter-intuitive coaching decisions for top level skaters. They are on record as forcing older skaters with bigger medals into these decisions.
Yuzuru Hanyu is a minor under Japanese law. This coaching change had to have been in the works for a while, before he won World bronze. Now I know Yuzuru is very talented, special and unique, but how would a 17 year old kid with no major senior wins find the gumption and clout to defy the well established traditions of the institution that governs his calling in life?
Or maybe, some of you insist, this is actually something Yuzuru initiated himself. Again, we have no evidence of this. We do have the skating director of the JSF on record as saying, rather paternalistically, that this change is "necessary" to "raise the level of Yuzuru's skating". This decision fits entirely with the m.o. of the JSF. On the other hand, how likely is it that a 17 year old kid would want to ditch everything he knows and everything that's worked for him so far and everybody he loves to move halfway across the world to work with strangers? It might be likelier if Yuzuru was having a bad season. Maybe there's some internal drama going on that we aren't privy to. But turn up evidence of that and we'll talk.
But, but, why doesn't Yuzuru have Nanami move halfway across the world with him, too? Because she has family, friends, other students and clients in Japan!
Now all this makes it sound like going to Orser is the
Worst Thing Ever. But really, it's not. Seemingly abrupt coaching changes and young skaters having to move to an entirely new country to train are nothing new in our beloved sport. Lots of skaters and coaches have survived this with their careers and feelings intact. So unless we get any indication that things did not go well, let's not be so hasty to assign blame to the skaters and coaches involved. Feel free to blame the JSF, though! I do agree with most in saying that this reeks of the old changing horses midstream error, especially when they were galloping along so well. And yeah, if it were up to me, Yuzuru would stay with Nanami in Japan. But I don't think this change is entirely bad with no positives whatsoever. I do think there's a good chance that everything will work out, and I look forward to seeing it!
