Was a great moment for the USA. I remember it well.
One of my other favorite moments was a few years earlier, when the Philadelphia Flyers mopped up the ice with the Soviets back in 1976... they were so roughed up, they actually left the ice, crying about how they were getting beaten up so badly.
NHL rinks are typically 15' narrower than the international rinks used in the olympics and that results in a more physical game.
That was one of the advantages the European olympians always had over the U.S.
