First of all, I am sorry, being off topic. I agree with you on this, but we should not forget Egonu (21y.o) and Boskovic (22y.o) is younger than Goncha. Goncha is 30y.o now. If you compare Egonu/Bosko with Goncha when she was 21/22, yes still they are better than Goncha imo.
OTOH, I have to admit that Egonu and Bosko's teammates in their NTs are better Goncha's teammates. Goncha scored 35 pts against USA in WCH 2018 but it was not enough because her teammates didn't contribute a lot. It was not her fault. I don't think Egonu and Bosko win the games on their own, reception, defence of Serbian/Italian NT is better than Russian NT. Not to mention, how perfect is Maja's sets to her teammates. When she was in D.Moscow, Fetisova contributed a lot and even D.Moscow defeated Vakifbank in CL last year.
And Goncharova got injured in the WCH, had she played against China, Russia would have a better chance. I think had Goncha played, Lang Ping would probably have played with B team, because Goncha would push Chinese Players really hard in the game....not something that Lang Ping wanted.
