I've said it a zillion times before; the semi-final game was the best performance by Team Canada vs. USSR in a clutch game ever. The odds were so heavily against them... they had a poor round-robin (2-1-2 record, eg. 3-6 loss to the Soviets), and USSR even without Fetisov were beating everyone. Yet Canada, if anyone, dominated the game and were fully deserving winners, biased officiating* or not. It was one the rare times when I've seen the '80s Soviet team look a bit disorganized, even KLM; great penalty killing & forechecking by Team Canada.
However, when you look at the team on paper and the whole tournament, I would say that it was rather the weakest CC team they had between 1976 and 1987, one great timely performance notwithstanding.
* I don't think there was any chance USSR was getting a PP opportunity in the OT (like CAN got), but it wasn't really something that decided the game
