I guess the highest-profile case would be Adeliia Petrosian, who has been pretty dominant in women's skating since 2022. She has said that she really wants to go, and frankly, as great as Sakamoto and now Alysa Liu have been, she does triple axels and all kinds of quads while still being strong in other areas. Her presence this week might have led to different results...
Her coach, Eteri Tutberidze, already is already allowed to coach at ISU events — she was with Nika Egadze this weekend, as usual — so I guess that's half the battle for Petrosian, yes? Given that the skater is still only 17, I imagine that the other half is a tricky as it might be for other athletes — she's young enough to have skated by restrictions set by IOC or ISU.
Yes, I know. it was a bad pun.
