Anything can aways happen. But the likelihood I would say is 0. Because figure skating has gotten so popular in Russia, they have tons of ambitious girls all with the same goal. Alina and Evgenia were nowhere close to the current skaters in their technical arsenal (both jumps and spins - the combination), neither now nor back when they were the same age. It only takes 3 to push both off a team. And when you have thousands of your girls who are starting to up their technique younger and therefore have much more time to work on it along with their bodies when they grow, the chances are next to nothing. It's even likely that the 3A will be replaced as the front runners in a year or two, as younger girls will be watching and be inspired by then to up their technical arsenal before they even get to where these are. Not to say that Alina, Evgenia, etc. aren't great skaters who can up their tech as well, but others are doing it quicker and earlier because they have the advantage of knowing what is expected. In any other country, this is not a problem, but when a sport is that popular, it's natural.
In a way Trusova (and Anya) started this revolution, and yet, I wonder if either of them will reap the rewards.
