@Vash01 im not sure if it's as easy as has it/has it not, when it comes to mental strength that produces champions

I agree mental strenght is of course needed. But for some it can be acquired or learned, in the most hopeless cases. It can come through experience and age - like Aliev, I actually believe he's on the right track, he's much more consistent this season than last year. Or Carolina.
It can come through switching to the right environment - like Butyrskaya, who clearly found herself with Tcahikovskaya, like Angela Nikodonov, or Adam with Raf, or Mirai, who says training for Tom S. works so well for her, because she's allowed to make mistakes, and is not expected to be perfect every time she skates.
Some perform better and more consistent after becoming a parent, like Suzanna Babiakova, as they get a different perspective on life. Some work with a sports psychologist and manages to overcome the problem.
Of course, some just have it, right off the booth, like Kwan or Plush. For Kolyada I hope the remedy is to compete, compete, compete. If he lands those jumps with good enough ratio in practice, he has to start landing them in competition sooner or later. Or water down, like Aliev, and gain consistency and confidence through lots of clean skates with only the quad toe, then add more later. Key is also to not loose the goodwill and trust of his federation. They should keep supporting him, they might get a diamond in return. I mean, they kept believing in Kovtun all those years, why not Misha. Some feds are good at giving skaters the time they need. I believe that's essential. But of course...Misha could be a hopeless case. Like Brezina or Sandhu....
