I don't think Zhulin is playing favorites at all? Or didn't you see S/K not being even close to the readiness B/S have at the moment, and I doubt they will in the current season. Also, I don't like much their SD, but it's their vehicle for the season, it works for them, and it' not scoring badly at all, the same with the FD. And where's the interview saying Zhulin was advised to scrap the SD? I didn't hear anything about that.
But where do you want them to go, and what do you want them to do? There's no way they are leaving Russia. No way. Dmitri has a son and Katia is married right now, they have their whole lives in Russia, and there's a good enviroment for them to train exactly where they are. And does Russia even has the money to send a skater to train out of the country right now? I don't even see why they should do it at this point, it won't make a difference to have half a season outside Russia. And if they want to change coaches, should they go to whom? Can you tell me honestly that there's a coach offering what they have with Zhulin in Russia?
And you should stop belittling their efforts, because it's their whole career on the line, I doubt it is something they are taking lightly. They are well trained, they are competing well. It could be better, yes, it could. Their mistake on the spin at COR took them out of the GPF, and the look on their faces at CoC said exactly what they thought of the scores they got. But people usually laugh at them protesting the scores, so I'm not gonna be the one to do that.
