I think Russia benefits from the postponement. I agree that Goncharova is not getting better but most players are not 30 yet. And the "old" ones (Startseva, Koroleva, Podkapaeva) should be able to play at the same level next year.
The good thing is that Russia has now more time to find the right players and system. And there are several interesting young players (Kadochkina, Kotikova, Fedorovtseva just to name a few) and some players below 25 who need the experience of another season (O. Frolova, Iurinskaya, Lazareva, Simonenko and more). Also we can still hope that we find more options for the setter position.
Kosheleva's chances to be part of the olympic team will be even lower next year (other OH are 5+ years younger).
