If there was anyone who should've played during WGP... I think it is Kosheleva. Goncharova needed all the rest in the world after playing through out the years.
It would've been perfect if they tested Voronkova as a receiving opposite while Kosheleva is a non-receiving OH or as a receiving OH while Kosheleva plays as a traditional opposite.
Kosheleva is lacking technique. She's supposed to kill it but a lot of blockers has been taking touches of her hits which slows down the ball. I don't know... This team is stronger than Turkey on paper but the chemistry is off since they have no fixed lineup.
As I said before... They should've gone down with Frolova good or bad but instead they keep changing the lineup with no direction at all as a team.
Ko lacks the technique bcs she never needed to develop it. She is (still) the highest jumper in female volleyball but now she's hitting the track of Bartosz Kurek, i.e. superb physique, decent wages - what else do you need? - but people know how to deal with her. There was a hope for her to improve in general when she was playing for Kazan some time ago. They pushed her a bit and she improved defensively a lot but then the ways had parted.
I do not know what exactly happened that made them change the coach. What was totally weird was that Kuzyutkin was still with the team, sitting on his chair all alone during the games. I'm just puzzled - it echoes another trick back from 2014 when they decided to play with Ko and Go as OHs and let Gamova play opp. This strategy works for Zenit Kazan though :).
