Everyone needs to improve, but running to Brian Orser isn't the answer in all cases. Kolyada lost ground not because of his coach, but because he was out for ages with an injury. He wasn't going to get the highest PCS this season when he is virtually unknown to judges. He has to complicate his programs gradually, but this can certainly be done without the help of Brian Orser. Plushenko has offered to help him if he needs it, Lambiel...not exactly poor help to have.
And by the way, Voronov did break through in his late 20s, unless you don't think being the #4 man in the world, with 2 Euro medals & a GPF medal, is worth anything. He made several improvements with Eteri in his late 20s & he may still improve with Goncharenko, we'll see. The only thing "old fashioned" I see about him, maybe, is the lack of transitions, but plenty of younger skaters lack them as well (Boyang, hello?).
Mika is pretty good spinner too!
And flexibility really does make men look better on ice. Not just spins but the ability to turn your legs all kinds of ways (basic ballet training, essentially). Although of course a reed-like built is not a guarantee of flexibility in and of itself, you still have to work on it. Plenty of narrow-boned skaters cannot do anything close to a biellmann. And, of course, in ballet men have to be flexible independent of their constitution and jump ability, they don't get free passes on that.
