Yes it does. If the Russian system focuses on skill rather than physical contact then you are bound to get more skillful player and less players who are physical. And that's exactly how it works now. For every Evgeny Artyukhin there are 4 or 5 Nikolai Zherdev's. It's not racism, they just breed players in a different manner.
Sure, but that doesn't mean Russian, or European players in general lack heart, grit and determination vs. a Canadian, as many have said here.
