I don't know if anyone agrees me but I have been thinking the same for a long time. Goncharova is indeed a great scorer, but she's never effective on important moments. Especially for high level teams, it's never so hard to stop her. Even though she scores as much as Gamova, there's a serious gap between those 2 players in my opinion. And today Russia definitely needed a leader attacker in the parts of the game that I could watch.
Congratulations to Russia and brave Brazil anyway
I also thought that for a long time. Today I think Gamova is the best spiker in the world and one of the greatest opposites, though I prefer Sheilla. IMO Goncharova will never be a hitter like Gamova, but she can be a better opposite. If she doesn't concentrate all her game in spiking and decides to improve her digs and blocks she could be better. Defence is very important. If you only helps spiking but have a lack defending you maybe is opening a good way for your opponents. I mean, if you score 28 points, but 27 spiking and 1 in service, it means that all time your opponent tried to pass your block and spiked on your side against your dig, they were successful.
If you score 1 point but didn't block or dig a spike against you, it's 1-1. If you score 1 point but touch the opponent spike with your block or dig, maybe you don't have time to spike for your team, but you generated a counter-attack and other player from your team will score. It makes 2-0 and you have an advantage. You don't need to be the best scorer to be the best opposite.
I guess Goncharova could block better than Gamova (a possibility here) and dig better for sure. If she does it she'll be a better opposite because her spike isn't like Gamova but it's very good. I only think it's hard to change mentality. It isn't a thing that happens fastly. Russian spikers usually don't particitate a lot at defence and russian MBs usually don't spike a lot. If we consider the current russian system, nobody is able to replace Gamova. If the system changes and MBs start to spike more and spikers start to defend more, I guess Goncharova has plenty conditions to replace her.
