Obviously they won the gold, because it's scientifically impossible to fail if Kurt Russell believes in you.
But they left out his best line. During their final showdown against Finland, when the Americans were down 2-1 after two periods, Brooks marched into the locker room, puffed out his chest, and gave the best sports pep talk ever: "If you lose this game, you'll take it to your f*****g graves." Then he paused and repeated "Your f*****g graves." That was it. That was the entire speech. It's like Don Cherry and Ernest Hemingway had a weird, bearded metaphor of a love child.
And, well, it kind of worked! The boys in (red, white, and) blue came back like screaming eagles to win the gold 4-2. So why would they leave out the most epic speech of Brooks' career? We don't know, but while America might have finally been ready for a movie about its miraculous Olympics win, it might not have been ready for Kurt Russell dead-staring the camera while emphasizing, "Your f*****g graves."
