Even at the start of last year we talked about how Ksenia won't be factor because Polinas were age eligible etc, and Russia wont need her etc. However, at the end Russia had to use her, and also her score did count towards ensuring 3 spots for Russia for this year. Remember Polina Korbeynikova royally bombed the worlds ... Polina Agafanova is shadow of what she was, Polina Shelepen has real problem with nerves. So Polinas may not be a factor at all.
Liza, Adelina and Elena will be really strong and hard to beat, in my opinion. This is based only on what they did last season alone. I would like to see how Liza and Adelina perform this year before fully putting them as favorites since it feels like a long time since i have seen them skate (partly because they are going to skate as seniors in championships and need to position themselves well in the eyes of international judges). A decent skate from should be enough for them to make the team. However tehy can struggle. As for Ksenia, i am not a fan but she did help Russia many times to keep the 3 spots. She is a strong SP skater and scores well. So, going into FP she usually positions herself well. Her performances usually are bad in FP but her skate order along with few landed jumps ensures she gets a good PCS (ladies competition can be bit of a splashfest as we, so other too ensures her position). Hence she does not sink too far. Unlike thes likes of Polina K and Shelepen, who usually does a disastrous SP. Their scores are bad in SP and they usually get bad skate order. They then have a mountain to climb after that, partly because of their lack of reputation.
If I was Russian Fed, I will not score Makarova too badly and wait and see how things plan out with the likes of Liza and Adelina. It won't be the first time that a very promising junior has failed to deliver. Saying all these i hope, I sincerely hope Ksenia Makarova will not make Russia team. hopefully this is because she lost to a group of ladies who delivered at the nationals.
