Yuzuru was just one of the most promising up and comers for me until I read some information brought here by a Japanese fan. (I can't recall who did or link it because I don't remember the thread title.) As I love looking into the mind of the skaters, (though unfortunately not much about the Japanese skaters is accessible or comprehensible to me,) sometimes something unique and special about a skater's mindset will catch my attention and curiosity to watch how they turn out.
For Yuzuru, it was reported he added Patrick Chan to his idol list when he watched Chan live at COR and how cute he was that, admiring Chan's skating, he wished to be able to ride on his back while Chan skated. I'll elaborate on what I wrote then. What really stood out for me were
1) He named non Japanese skaters to be his idols instead of the traditional citing of senior compatriot skating stars, indicating his mind not being litmited within the proverbial box, and his not being concerned about stating his unconventional choices.
2) He had several idols he looked up to - Plushenko, Weir, Chan, and, I'm sure, others. I realized then he would be an excellent all round skater, modeling the best in different aspects of skating. Again an open high aiming mind with no usual self imposed limits.
3) His desired way of learning Chan's skating skills indicated he learned in a very different, unique, and probably the most effective way. He wanted to feel Chan's skate as if he were him. I think he's able to learn by "absorption", by "being" rather than copying, and is instinctive in picking up skills through his mind power instead of the unsual ways of being taught and physically drill trained. Even right there in COR practice, he imitated Chan and found himself skating faster. That was very quick learning as he immediately put something new into practice. Right then I expected him to rise in his skills and techniques very rapidly.
As of now, mere months later, these feeling I had about him are being borned out as shown in his amazing jumps and out of ordinary combinations and unique ways of coming into his elements. I have no doubt his presentation will improve to a very high level as well. I don't have any information or knowledge about his competitive mind, so I can't say how well he will bring his skills into competitions. Presumably, he aspires to achieve as successfully in competitions as his idols. The only probable obstacle then is his asthmas and I wonder if he would overcome that with his mind.
In passing and OT, a new young skater who has piqued my interest in her future due to an indication of her mindset is Christina Gao. I was very impressed with her beautiful skating when I first watched her in the Olympic year and thought she would be the future of US Ladies skating. I have not followed her closely since but was impressed with a recent interview in which she aspired to be dominant like Patrick Chan. Why am I impressed? Well, I had just listened to questions and answers from various skaters in the US Champs Camp. In citing which quality each skater would love most to have from any other skater, each of the Ladies cited a recent successful female skater. No one said anything like I would like to have Plushenko's quads or Lambiel's, or even Ruh's, spin. They limited themselves even when the question was about fantasy, choosing to be "realistic" or not to appear over ambitious. Gao didn't limit herself by gender and she was modeling someone's achievement and mind rather than particular skills, just as Chan models after Federer and Kwan for their dominance.
There are many other important factors for success, intrinsic and extrinsic, and I have very limited knowledge about either of these young skaters, and of most of their competitors for that matter. However, I do consider the mind the most important and most intrinsic basis and predictor. I wouldn't be surprised to see great accomplishments by either.
