Future, I understand the reason for your sarcastic post (the user you replied to was rude). But I would try to explain you my point of view, as someone who also thinks that most skaters lose their magic after leaving Tutberidze.
Every time I watch a competition, I myself am awed how much better Eteri's skaters are (presumably, they also skate clean). There are a lot of young ladies from other coaching teams that have better technique, have better spins or skating skills, or are born performers, but they can never build the "whole picture" for me. Despite the strategic layouts and trainings, I cannot unsee the attention to detail in Team Tutberidze. Of course, their skaters are not 100% perfect, they constantly have to work on improving, but generally despite the technical part, they excel on n extensions, equal arm and leg involvement, nice hits of the music notes etc. Due to the trend in the past years, we see more and more teams trying to integrate this style but still they don't reach the same effect. Just hitting the music accents or adding some rippons, doing fancy combos is not enough..because a wholesome concept for the certain skater is missing. That's why I also thing that anyone could alure her entire coaching team (Daniil, Dudakov and Zheleznyakov), and the skaters training with them would be very good... but would never reach this uniqueness, because the artistical idea of how someone should develop in the following X years won't be there.
Edit: this doesn't mean that Sasha and Aliona got worse or something. For Sasha nothing changed for me on the exterior, she is focusing on improving her technique, but this was always her main priority. Aliona is suffering more from puberty and injury right now than from leaving Eteri. On the long term, I see, however, a possible problem to find the suitting style for her.
