The 30s is when they started playing hockey. I keep mentioning that they were newcomers to the sport of hockey, because the notion that the Russians/Soviets brought, say, the east-west game to the sport shows a major lack of perspective. So I was hoping that providing some additional context would clear it up, but it doesn't look like it's working.I don't really see you saying anything that actually contradicts what I've said. Forward passes weren't around until the 30's so we're talking about basically 10 relevant years during which Latvia wasn't part of the Soviet Union. Like I said, essentially all of the relevant time period. It seems you're focused on making sure Latvia gets credit but I'm not talking about Russia vs. Latvia so that's your hang-up.
The only reason why I can give you details on the Latvian involvement in early Soviet hockey is that I'm... Latvian. It's got nothing to do with me trying to get credit. I wasn't there myself, you know. As I already said, the Czechs played a major role as well and if I was Czech, I'm sure I could tell you some more stories and factoids about it too.
Furthermore, hockey was brought to Latvia by Swedes and Brits and they had contacts with Canadians before that. I'm just telling you how modern hockey spread in Europe. It's got a much longer history in Europe than in Russia and all of their 'innovations' at that stage were, well, not really innovations at all.
Also, I honestly don't understand why you keep mentioning that Latvia was invaded by the Soviet Union. Did France become a part of the German culture when it was invaded in 1940? Frankly, it also shows a lack of general historical perspective and it's a bit insulting. The Latvian hockey traditions/culture were continuous throughout the 30s/40s. Just because there's a foreign army present doesn't suddenly make us a part of the invading countries' hockey culture. You seem to be fixated on the name of the political establishment the Latvians were playing for, but it has nothing to do with the way hockey spread in Europe and Russia, which is why I brought it up in the first place.
Tarasov did bring some new methods in coaching in the 60s/70s, that's true. Chernyshev, who was the head coach of the Soviet national team during that time (Tarasov was the assistant coach), was coached by, you guessed it, Latvians.
I'd say that the sheer amount of talent was the deciding factor in all of it. It's not the strategic approach to the game which made them so dominant.
