There have always been certain amount of girls who looked very promisisng, but puberty and injuries prevented them to stay at that level or transfer it successfully to seniors. It is very sad, but it's life. When watching Sakhanovich from 3-4 years ago, it makes me feel quite sad too. It shows how one can't make predictions based on junior success. From those four newly eligible that season, I liked most Proklova and Sakhanovich, and much less Medvedena and Sotskova. But no one could predict which of them would make it to the top, which of them will be in contention (not quite on top but still in the group to be counted), and which of them will not make it at all.
Proklova had it all. The style, the line, the flexibility, the musicality, the jumps, the spins, everything. That's the pity. Almost every other up and coming Russian girl had something that wasn't right. Not Proklova.
Sakhanovich was always that girl with ugly tanos, jump landings with no flow and break at waist, and the world's worst 2axel. The lovely flow and spins could only help so much. She doesn't have a GP but I don't think her senior career is over yet. When even Leonova can have 2 GP events, I think there is plenty of time for everyone else.
