If you mean that all russian skaters are like Adelina you're dead wrong.
Osmond's career lasted just as much as Elena Radionova, Anna Pogorilaya (which technically they are still not retired),...
Tuktamysheva is still there competing after 7 seasons in seniors.
Comparing Osmond and Mao careers is also not fair considering Mao competed for more than 10 years in seniors, and went to both 2010 and 2014 Olympics.
I was speaking about longevity and medals, are this the top skaters on their fed? no
