Eteri, Sergei, Daniil, Sergey Rozanov, etc., the whole team, they work together. TOGETHER.
Let's look at Alina. She came to Eteri at age 12 with what? a triple salchow, double axel, triple loop? Two years later, she's got the most technically demanding junior program we'd ever seen at that point. That isn't all Daniil's accomplishment. A lot of it is, but a lot of it is also Dudakov's, Tutberidze's, etc. They're all working together to give each student what they believe is the best.
Look, I don't agree with how Eteri's acting now, and I think it's petty and immature. But that doesn't mean that she hasn't done anything as a coach or that it's okay to diminish what she has done. She built Evgenia from the ground up and made her as good as she was, long before she had a team like Duadkov and Gleikenghauz working alongside her. She took Yulia through Sochi, and yes, what happened afterward, but she gave Yulia experiences and success she never would've had in Ekaterinburg. She took Polina to the top and it's not her fault that Polina keeps getting injured -- she seems to have something that makes her more prone to injuries? as far as I know. She took Alina in and made her a star, with the help of her team. She made Tarakanova more consistent, brought Kostornaya back after everyone thought she was done, gave Trusova better tech skills, made Akatieva possibly the best skater of her age that we've ever seen, brought success and quads to Shcherbakova even after those horrible injuries, coached Panenkova to good scores and incredible jumps, and the list goes on and on. Yes, she's flawed, and yes, she's done some very questionable stuff, but that doesn't take away from the good.
