I feel pretty confident that regardless of who Russian sends to Worlds, they will most likely not sweep the podium. Right now it seems pretty clear that, barring meltdown, Medvedeva will be on the podium along with 2 of: Radionova, Miyahara, Asada, Gold, Wagner. Worlds being in the US is going to help the US ladies have more of a realistic chance, Radionova has a good shot of getting on the podium, but even she could wind up off it. Any other Russian lady, be it Liza, Anna, Julia, Adelina, or anyone else, will get thrown into the medal mix as a wildcard along with Polina Edmunds, Rika Hongo, with a very very slim chance of getting onto the podium - the stars would really have to allign.
Gracie's victory over Polina at Nationals and Evgenia's victory over Lena at Euros showed that this sport is very political. I'm not saying the outcome of those 2 events weren't right, but it does show that skating 2 clean programs isn't going to be enough for someone to win if you don't have the reputation to back it up. Polina didn't medal at either of her GP events and didn't make the GPF, as long as one of Gracie or Ashley didn't completely blow it at Nationals, one of them was going to beat Polina even if Polina was perfect. After Evgenia won GPF and Nationals so convincingly and Lena was a distant 3rd and 2nd at those events, it was clear that Evgenia skating decently well would beat even a clean Radionova at Europeans.
Liza doesn't really have any big reputation points that she earned all season. She lost to Ashley at Skate Canada, she was 5th at TEB, she didn't make the GPF and she finished 8th at Nationals. She had a couple of decent skates at some B events but she wasn't spectacular at them and she didn't compete in enough of them to really build any momentum. Julia, Adelina, and Anna similarly don't have momentum from the current season. Of any, Anna arguably has the most because at least she was 3rd at Nationals and got to compete at Europeans where she was 3rd. But anyways, the only way any of these girls is getting on the podium at Worlds is if at least 4 of Evgenia, Alena, Mao, Satoko, Gracie, Ashley make really significant mistakes there. Barring several meltdowns, I fully expect the podium at Worlds to come from this group of 6 girls.
The Russian Fed can do what they want, but I won't be surprised if whoever they send doesn't skate well at Worlds and I really don't think we'll see them on the podium. Unless Liza has a complete turnaround and is fabulous at one of these upcoming competitions, she'll go into Worlds knowing that she hasn't skated well most of the season and didn't really earn her spot on the team on top of having the pressure of defending her title and having the Russian Fed expecting her to skate 2 clean programs.....sounds like a recipe for disaster to me. If they don't send Anna (the logical choice given Nationals results and that she was 3rd at Europeans, which she would have been skating perfectly anyways), the Fed should consider sending Sotskova for experience. She has been consistent this season unlike any of the other ladies in the conversation, there wouldn't be pressure on her to medal, and it would help her gain exposure leading into the GP next season.
