The point is not the "next couple years." No one is winning an Olympic medal in the next couple years. Abachkina & Drozd could have the potential to bring home many medals over the course of a full career. Or . . . they could implode just like Abachkina & Thauron did quite often in major competition.
There's no way of knowing there.
I actually agree with DimaToe. But my guess is that there is no way Russia trades Stolbova because trading away an Olympic & World medalist would set a precedent the Russian Fed probably doesn't want to have to confront in the future. Theoretically, trading away Drozd seems more likely. But it's folly. There are not twenty more of him in Russian ice dance. It would, IMO, be like trading away Anissina. Very likely to come back and cost you big time.
Does Russia have the power to get both Novoselov & Abachkina? We may find out. Or we may never know.
Realistically, Stolbova COULD medal at the Olympics in 4 years, but ONLY if some things shift big time. Drozd definitely has talent, but I think it will take a while to come to fruition with him.
it sounds crazy to trade away your Olympic silver medalist, but I wouldn't put it past Russia.
Ideally Russia would be able to keep them both. But I don't want to be the one who has to fight Didier for them
