they will withstand puberty and still beat Osmond
I wouldn't dare to bet on any single skater to withstand puberty, but considering the numbers of very talented young Russian ladies that are coming through, I think it is very likely that at least three will definitely withstand puberty and be ready. (unfortunately it is hard to know which three). And because at worlds and Olympics 3 per country is the max, the chances are pretty good for Russia (but not that good for each of them because the competitions among them for the three spots will be harsh.)
