Looking at the 2018 -2019 team who are the leaders. I would think Evgenia and Alina (as long as puberty doesn't set in) are the leaders but the third spot Sotskova has not donewell at the big events. How Anna P doing? Or could Liza T or Radinova sneak back on the team. There is also Polina T but she seems tobe always injured. At there best I would go with Evgenia Alina and Anna.
If the third spot doesn't go to Daria, Polina, or a CSKA girl, I would be VERY surprised... (unless it's Konstantinova :disapp

Personally, I think Daria will do very well this year due to her insane jumping ability and consistency. Polina also has insane jumping ability (that height!!

) but her consistency hasn't been there this season. Whether that's because of injuries or just how this season went, I'm not sure, but if she gets the consistency together, she could fight for the third spot.
If both Daria and Polina are in full force, or even if one of them is, I doubt that Maria will get on the team, unless it's purely because of the CSKA bonus (which I can't stand... why CSKA??? their skaters aren't even as good as Eteri's!) Her URs have really started to get her and while she skates well enough at worlds to be in the top 10 and save the spots, I don't think it will be enough, especially considering that she peaks way too early, for the GP series and the GPF.
I really doubt Liza and Lena can make it back onto the team unless one of them pulls a MAJOR change and upset, and even then it might not be enough. Liza still does 3T-3T and a sequence in the free (despite her wonderful jumps :disapp

and Lena has never had a non-questionable / non-scratchy landing in the past two seasons (that might be an exaggeration but not much of one unfortunately) I understand that Russian Nationals are fierce, but Lena was lucky to be 9th there and was saved on PCS thanks to CSKA bonus. Liza did respectably well but next year Trusova and hopefully Shcherbakova and Tarakanova will also be there and both of them have much better tech content than her.
YMMV
