No that's unfair, and I speak as someone who gets absolutely nothing good or bad, just a void, from Nathan's skating. He has fans in other countries with reason, he is great at what he does and while his personality seems to be very ordinary, it also seems to be a good man: pleasant, hardworking and as generous as Yuzu or Javi. He will have fans, just as any top athlete does, and he and they need to be respected.
But I don't believe for one minute he will ever be - and probably doesn't want to be - as loved and revered as Yuzu at home or worldwide (the only one I can think of who was near is Plushy. Oh, and Yuna of course). He also won't be the saviour of the sport in NA that they are hyping and hoping for. He doesn't have a country that cares very much. Nor does he - nor any of the others, not even Shoma or Javi - the lighting in crystal aspects Yuzu does, the bishonen appeal, the unearthly emotional connection with his audience, the love and respect of a whole country, the vulnerability, the tragedy and triumph, the symbolism of being Sendai's hope and the phoenix, the symbol of courage and strength for the people who have needed it.
There are many sporting legends, and Nathan may well become one of them. But Yuzu is a legend in many more ways, more than human and all too human, to many of his people, and I wouldn't be surprised in the years to come if he is named as a national treasure.
