Russia doesnt have really good setters to choose right now so they are stuck with Startseva and Kosianenko. Kosianenko is pretty ok but Startseva is just so-so. Among the OHs Pasynkova is most likely the one to be replaced by Kutyukova or Ilchenko since FD is a focused for the team right now. Lyubushkina is a team player. She gets her job done but doesnt do anything exceptional. She can easily be replaced by Morozova or Shlyakhovaya depends who will recover from their injuries faster. Bavykina is a future scoring machine for russia. Her FD is pretty weak but very good attacker. She can play OH2 if needed. Im afraid Gamova or Sokolova will be in the line up but hopefully it will be Gamova.
Kosianenko is better than Startseva right now and she should be main setter. Besides, half of the NT are players from Dinamo Moscow so it's really a no-brainer decision for Marichev. For second OPP, no way Bavykina will be used over Malykh, and even then, both may lose their spot if Gamova joins into the picture. With regards to Pasynkova, she may not even be used for reception but as a serving specialist. For example, she may come in when error-prone Zaryazkho is serving for crucial moments as she has good serves which are somewhat tricky for the opponents to receive (she and Fetisova are the most prolific in terms of serving) so although she is useless in attack, she still has her role in the team. The question is if Marichev will bring 3 OHs as she will be competing a spot with Sokolova. Both have about the same level of reception, Pasynkova is slightly better in serve and block IMO, but Sokolova has the experience and has stronger nerves and it's not like both are being used as the team's primary offensive options anyway. I think the deciding factor whether Marichev brings 4 OHs or not will depend if he decides to add another libero as that will already exceed 12 players.
