A number of them peaked as juniors. You can never tell what effects puberty will have on their skating. But I also think it's possible some of them made ill-advised coaching changes at some point. Some people in the skating community were calling for Liza to leave Mishin after her disastrous season. If she had done so, I doubt she would have made a successful return like we have witnessed this past few months.Lots of videos have been recently made about russian ladies.
Just found an old one about rising figure skating stars
Some of them have already won titles, others we may not ever see again.
This makes me sad
