With all due respect, but this repeated "meh meh only little waifus means nothing what they can do at 13 they'll all be gone and burnt out by puberty" starts to sound like nothing but sour grapes about the general success the Russian girls and specifically Eteris group has. If they make it through puberty or not is irrelevant to how impressive it is what these girls can do now. Eteri and her team are also still really young and she has majorly taken on younger girls - how about we give her some more time to see how things look like when a big number of her girls have reached 16 to begin with? No? How many girls did she "lose" anyway - Yulia, and then? I'm not seeing all that much proof for these "they burn out after 1 or 2 years" stuff. Evgenia might as well not be the exception, we just can't say yet. But if you're putting your hopes on all of Trusova, Tarakanova, Shcherbakova, Panenkova, Kostornaya, Zagitova and Tsurskaya to be nowhere in the next years.... prepare to be disappointed. (and that's not going into the other girls Eteri has that aren't even age eligible for Juniors yet, or the talented Russian girls that aren't with Eteri).
And what's there to be so upset about over Gubanova? She had trouble at her JGP, which is a shame, but she skated 2 clean programs just the event before that. If you're willing to write her of after just that you might want to re-think you're fan standards and not the abilities of these girls.
