Care to calm this hyper worried Hanyu fan

? I see people already saying that Yuzu's time as the King is over and such... I have lots of things happening IRL now so i don't have the concentration to sit and analyze the situation so can someone tell me with apples and oranges how much of a threat Nathan could be for 2018? I don't feel like he could snatch the World title simply bc i feel like Yuzu hasn't peaked yet, my main worry is Olympics...
Yuzuru's time is of course not "over", but Nathan Chen
is a definite threat...
I know US commentators and fans are hyping like crazy, and for good reason... but, I think he still has much work to do before the 2018 Olympics. IMO, Skating Skills, Transitions and Interpretation for PCS, and hitting more GoE bullet points for the TES. In particular, his arm and leg movements are beautiful, but they disguise transitions that are very lacking in variety, vertical movement, and balance-threatening upper body movement.
Of course he will be working on all that (and more)... but it is no simple thing to improve that stuff. It's difficult, and it eats away at the skater's speed, strength and stamina... and in turn, if those are affected , it becomes harder to land the big jumps consistently and get high GoE. On the other hand, there's a whole year to go, and a lot can happen in a year. We just have to wait and see how much he can improve.
Yuzuru won't be standing still either though (and nor will Uno, Jin, Chan, Fernandez etc for that matter). Yuzuru watches (studies!) them all... and he will do whatever he can to stay one step ahead of them... he will not simply stand still and let people overtake him without a fight...!
So... a definite threat, and he is surely destined for greatness - but
how much and
how soon remains to be seen. These are exciting times, and I think Nathan Chen is exactly the kind of threat/challenge/rival/competitor that Yuzuru
needs, to bring out the best in him...!
