With the Olympics being postponed to 2021, this hurts Russia more than it benefits them. The team's main offensive weapon, Goncharova, will be 32 years old by the time (Kosheleva will be 33). If I remember correctly, Gamova was also 32 years old and Sokolova was 35 years old during London.
Russia should really start looking for Goncha's heir-apparent this year. If not Lazareva, maybe Kadochkina is the answer.
