Miracle on Ice

Context: Vladimir Krutov was sent to the penalty box at the 6:47 mark of the third period for high-sticking. The Americans, who had managed only two shots on Myshkin in 27 minutes, had a power play and a rare offensive opportunity. Myshkin stopped a Mike Ramsey shot, then U.S. team captain Mike Eruzione fired a shot wide. Late in the power play, Dave Silk was advancing into the Soviet zone when Valeri Vasiliev knocked him to the ice. The puck slid to Mark Johnson. Johnson fired off a shot that went under Myshkin and into the net at the 8:39 mark, as the power play was ending, tying the game at 3. Only a couple of shifts later, Mark Pavelich passed to Eruzione, who was left undefended in the high slot. Eruzione, who had just come onto the ice, fired a shot past Myshkin, who was screened by Vasili Pervukhin. This goal gave Team USA a 4-3 lead, its first of the game, with exactly 10 minutes remaining to play.  The Soviets, trailing for the first time in the game, attacked ferociously. Moments after Eruzione's goal, Maltsev fired a shot which ricocheted off the right goal post. As the minutes wound down, Brooks kept repeating to his players, "Play your game. Play your game." Instead of going into a defensive crouch, the United States continued to play offense, even getting off a few more shots on goal. The Soviets began to shoot wildly, and Sergei Starikov admitted that "we were panicking". As the clock ticked down below a minute, the Soviets got the puck back into the American zone, and Mikhailov passed to Vladimir Petrov, who shot wide. The Soviets never pulled Myshkin for an extra attacker, much to the Americans' disbelief. Starikov later explained that "We never did six-on-five", not even in practice, because "Tikhonov just didn't believe in it". Craig kicked away a Petrov slap shot with 33 seconds left. Kharlamov fired the puck back in as the clock ticked below 20 seconds. A wild scramble for the puck ensued, ending when Johnson found it and passed it to Ken Morrow. As the U.S. team tried to clear the zone (move the puck over the blue line, which they did with seven seconds remaining), the crowd began to count down the seconds left. Sportscaster Al Michaels, who was calling the game on ABC along with former Montreal Canadiens goalie Ken Dryden, picked up on the countdown in his broadcast, and delivered his famous call:  11 seconds, you've got 10 seconds, the countdown going on right now! Morrow, up to Silk. Five seconds left in the game. Do you believe in miracles? YES!  As his team ran all over the ice in celebration, Herb Brooks sprinted back to the locker room and cried. In the locker room afterwards, players spontaneously broke into a chorus of "God Bless America"  and received a congratulatory phone call from President Jimmy Carter.  During the broadcast wrap-up after the game, ABC Olympic sports anchor Jim McKay compared the American victory over the Soviet professionals to a group of Canadian college football players defeating the Pittsburgh Steelers (the recent Super Bowl champions and at the height of their dynasty).
