He has - including galas - skated seven times at the Olympics. One was definitely faulty, one wounded but still magnificent, the rest both brilliant and iconic (as was the wounded one with its 6 million youtube views). The proof is on the Olympic Channel. Chen has performed three times, once brilliantly, the other twice... let's be fair, what's abysmal sauce for the goose is twice so for the other goose.
Yuzuru is also IMO being damned at the minute in some quarters by a heftily sour dose of tall poppy syndrome, which Patrick also got and which Nathan Chen probably will in his time. But the simple fact? They are both brilliant, the best our sport has to offer, and dearly loved by their fans. That Chen is a great champion but - in his own country - an undervalued and relatively minor sports star and Hanyu is right on track in his to be a national living treasure is just the way the geographic, historic and charismatic/imaginative cookies crumble (I'll happily admit, adore him as a skater as I do, the almost unbelievable social and emotional impact Yuzu has is just as fascinating in its way, someone needs to do a PhD on it and they will, they will)
I recall that in the green room at PC, as Chen had to collect himself and leave, Yuzuru is said to have told him "your time will come." And yes, it's now, and maybe it will last till 2022 and maybe it won't (this time in the Sochi quad, Patrick's time was believed to be right on track for Sochi). We don't know.
