I am not disappointed at all because from the very beginning I was realistic and knew that the coach change would lead to a rough season. But she has already had similar problems -in her junior years, even at her senior tribute - she skated her first clean FS at the GPF. Even though her last seasons were awesome, she still knows struggle and I hope she finds some strength this time too and overcomes those issues.
She and Brian are taking the long road in order to improve her technique and only time will show if this was the right strategical choice. Some people are, in my opinion, maybe right by saying that this approach won't work in her case because Russian ladies are far too good..and too much, so Evgenia has to work only on her Lutz and 2A, and the rest has to stay the same at her current level. But this is at the same time not possible because for better jumps she needs better speed and this requires working on basics like the SS.
From my observations of Pluschenko's academy, I have noticed that he has a similar approach with Tarakanova, for example. Although he's not an experienced coach, I believe he knows what it takes to teach good technique and I guess it shows that Brian is not totally out of his mind by doing the same with Evgenia.
What I am trying to say is..I guess.. that it couldn't have been better if she had stayed in Russia. I haven't been a fan of Borser but I don't think this was a wrong choice. She was struggling last season too, even before the injury but no one was blaming her coach. Such things happen - injuries come, the body grows, everything is constantly changing. Osmond had problems with her FS for 2 seasons but still made it to the Olympic podium and people were happy for her. So, why can't people be happy about Evgenia, too.. that she is not giving up and is still fighting, even though all the odds are against her? Regardless the results, I will always support this strong girl.
About AC - I think she could sell the tango only when she's secure on the technique because only then she would be able to relax a little bit and pay attention to the character of that particular piece. She was skating through the music in her SP, as well - understandably due to her nerves, so I don't really thing that the tango specifically doesn't suit her. She hasn't had the chance yet to fully dedicate herself to the music. It's interesting also that her worst jumps, the ones they are mostly working on (Lz and A) have the best exits so far. Yes, she messed up 2 from 3 Axels but when she nails them, they look very good. I even think that her 2A will become my favourite jumps of her. And this gives me hope that with time we'll see more visible improvements. The only strange thing is her Loop - even at the test skates she had some problems and now the fall. I don't know if they are working on it or if they don't. Because I don't see any changes in her technique there - so my speculation is that they have left it for later, since it was her best jump. But as we see, no work on it leads to problems too.
