Interesting, thanks for the video.
As DATS said, we aren't likely to see such dominance again. I didn't realize the army guys trained 300 days a year, and that was from morning to night. They played on the same lines since childhood. A life of dedication like that is becoming a rare thing in modern society. People value their free time. Larionov (and Fetisov) couldn't take it anymore, the pressure and drudgery, all while dealing with Tikhinov's verbal abuse. The players were fracturing like the Soviet Union itself.
I like the history from the Canadian perspective too, was intrigued by that documentary about the '72 series. It's always been a miracle that a nation with so small a population could produce that many great players. A bunch of 1/2 drunk hosers taking on the entire Russian machine is impressive haha. It really was a battle of ideologies- communism vs. capitalism, and the greatest hockey rivalry of the 20th century.
