If Sokolova and Hodunova are among the 15 best players of Russia, Russian volleyball definitely has something to worry about.
The little I saw of Hodunova in Russian Cup F4 did not look to me like she's the next big thing. Russia better hope that Kosheleva and Scherban stay healthy and in shape for a long time
Sokolova might not be one of the 15 best anymore, but she fills a relevant function to the team now since Kosheleva struggles so much in reception nowadays. Nothing new, but this season shes been a living powder keg in that regard. Therefore the team are obviously in desperate need of a stable receiver that can emancipate some burden on the main target Kosheleva which is a space that can be covered by Sokolova. Her attack has declined gradually since like 2010 but I believe she still might be one of the most adequate players in this kind of role for Russia now and therefore required for the sake of the system rather than her capability overall as a player. However, I also consider Scherban as a appropriate candidate for this kind of task and I hope she will get a shot in the starting lineup but I doubt it.
