The Soviet Union had won the gold medal in five of the six previous Winter Olympic Games, and they were the favorites to win once more in Lake Placid. The team consisted primarily of professional players with significant experience in international play. By contrast, the United States' team, led by head coach Herb Brooks, was comprised of mostly amateur players. With only four players with minimal minor-league experience, the United States was the youngest team in the tournament and in U.S. national team history. In the group stage, both the Soviet and U.S. teams were unbeaten; the U.S. achieved several surprising results, including a 2–2 draw against Sweden, and a 7–3 upset victory over second-place favorite Czechoslovakia.
