I don’t think there’s enough information out there to rank any of the US men except Nathan into groups yet, because none of them have performed “consistently” at the listed 2021 competitions.
At this point, we don’t even know if all the 2021 competitions will take place. If they don’t, it looks like they will at least consider including 2020 results. But assuming that’s not necessary, if you look at results from the 1-2 competitions Jason and the up and comers have participated in so far (Nats/Worlds 2021 for Jason, JGP 1 for Malinin, and 2021 Nats/Cranberry Cup for Paniot, Hiwatashi, Naumov, Ma), Jason’s scores of 276, 262 -while somewhat lower than his international PB/2020 scores - are higher by far than scores for the others. Malinin won his JGP with a score of 214. Ma, Hiwatashi, and Naumov all scored between 205-244 at Cranberry Cup and Nats. While Paniot did score 266 at Nats, he only scored 210 at Cranberry Cup. So while Jason is absolutely not assured a spot, he’s currently in a stronger position than the up and comers. And yes, this could change.
By the way, I haven’t heard anyone say that Jason was more responsible than Nathan for retaining 3 Worlds spots and giving the US a chance to qualify a third Olympic spot. But Nathan’s score alone wouldn’t be sufficient if Jason had not placed where he did. If Vincent does succeed in qualifying the third spot, it will have been a team effort: he wouldn’t have had the opportunity to skate at Nebelhorn but for the combined efforts of Nathan and Jason.
