I would agree with that - Russian skill development is remarkable given how few players they have to begin with. I would hope that Fetisov in his desperation doesn't try to fix what is not broken.
I have something I'm curious about - perhaps birthplaces are reported differently in Russia, but I've noticed that almost all of the players are coming from large cities. Like it is surprising to me when I see that Voronkov is from Angarsk, which is only ~200k people, because everyone else is from a bigger city. In Canada we have hockey rinks in every town, whether they have ~10k people or ~100k, and occasionally players like Cozens come from those small places. It is actually becoming a rarity in Canada though because those smaller places don't get advanced skills training. It used to be that a disproportionate number of players came from small prairie towns, like Gordie Howe did. Now they disproportionately come from Toronto, because you need to be there and have a lot of money in order to hire skills coaches. For instance in my home province of Nova Scotia, we have Mackinnon, Crosby, and Marchand from Halifax, where half the population lives, while the players from the rest of the province are incapable of winning a tournament at any level. Russia needs to add more rinks but expanding skills training to cover that area is a whole other problem.
