My two cents:
Team Canton seems quick to attribute their successes to Zoueva (perhaps more generously than she deserves).
Example: I remember that one time as Davis/White were leaving Kiss and Cry after a Fledermaus performance that the crowd and judges loved, White spontaneously faced the camera, gestured toward Zoueva, and said with a big smile, "It's all her" (as if D/W had not contributed their significant talent and hard work!).
So on the other end of the spectrum, it seems natural enough to me that when things don't go so well, Zoueva's skaters look to her -- because they want a solution, not because they are blaming her.
Sure, Moir would not be happy with their levels, but that does not mean that he was lashing out at Zoueva. At least in the press conference video clip, when he was saying that their coach(es) [I forget whether he used the singular or plural) would identify V/M's deficiencies, his tone was calm and neutral, not bitter or accusatory.
