Herb Brooks: Red line, back. Blue line, back. Far blue line, back. Far red line, back. And you have 45 seconds to do it. Get used to this drill. You'll be doing it *a lot*. Why? Because the legs feed the wolf, gentlemen. I can't promise you we'll be the best team at Lake Placid next February. But we will be the best conditioned. That I can promise you.
There indeed was a moment in the game (vs. USSR) where Jim Craig was shaken up, but contrary to what's shown in the movie, the hit did not happen as the Soviets scored a goal. Furthermore, if a goalie is that flagrantly knocked down and out so that a teammate can get a shot off, it should be a two-minute penalty for "goaltender interference" and the goal disallowed.
The 3,000 extras used to sit in the stands and act as crowd noise did an excellent job of chanting "USA! USA!", especially since they were all Canadians.
