Appropriately, given the location, it was as though an Iron Curtain descended across the Team Canada blueline.
Thou shall not pass.
And the Americans, scorers of 20 goals in their previous four Olympic matches, just couldn't figure out how to do just that. In the end, Carey Price delivered the goods with 31 saves in a taut 1-0 Canadian win, but he's had more quality chances to deal with in various five-minute segments this season with the Montreal Canadiens.
Team Canada was, quite simply suffocating. This was nothing like the 6-5 win in '72 or the 6-5 win in '87. This wasn't about Canadian firepower, but rather about Canadian committment to details and selflessness.
Team Canada has now won three straight games by one goal - 2-1 over Finland, 2-1 over Latvia and 1-0 over the Americans - and shown a remarkable level of defensive excellence along the way.
The Americans may have had 31 shots, but they didn't have many high-quality chances, the kind you need to beat the goalies you confront at the Olympic Games.
U.S. defenceman John Carlson - the same fellow who broke our hearts at the world juniors in Saskatoon a couple of years back - walked into the slot in the first period and forced Price to make a nice glove save.
And that might have been the best chance of the game for the Americans.
Jamie Benn, on a re-direction of a clever goalmouth shot/pass from Jay Bouwmeester, gave Canada a lead in the second. After that, it was as though there were two Canadian checkers to every one American attacker, backside pressure at all times, and the talented U.S. struggled desperately to make clean entries into the Canadian zone against a Mike Babcock-coached team that played a nearly perfect positional game.
Given that L.A. Kings goalie Jonathan Quick was dazzling in the American crease, and given that the Canadians couldn't come up with a second goal, that defensive effort had to be perfect. Even when Quick was pulled for an extra attacker in the final minute, the U.S. couldn't organize one clean, unobstructed scoring chance.
The victory secured Canada's 25th medal of these Olympics, as Team Canada is guaranteed at least a silver against the Swedes on Sunday. Over the past three days, however, there's been a gold rush for Canada, and with the Swedes going into that game without Henrik Sedin and Henrik Zetterberg, Canada will be favoured.
Price, meanwhile, has allowed only two goals in the Olympics, paying back the vote of confidence the Canadian coaching staff showed in him by giving him the No. 1 job ahead of Roberto Luongo, who had backstopped Canada to a gold medal in Vancouver four years earlier.
"I'm truly blessed to be where I'm at. I'm truly grateful for all the support," said Price.
The Canadian blueline pairs - Duncan Keith-Shea Weber, Drew Doughty-Marc-Edouard Vlasic, Bouwmeester-Pietrangelo - made few puck errors, while the defensive excellence of players like Benn, Jeff Carter, Patrice Bergeron and Jonathan Toews shone on the Canadian side.
Maple Leaf winger Phil Kessel had a few chances, but nothing great, and was forced to take a penalty late to difuse a potential Chris Kunitz scoring chance. The much-scrutinized combination of Kunitz and Crosby was goal-less for the fifth straight game, but they, along with Bergeron, were very effective in being able to sustain pressure in the U.S. zone.
The Canadian women's team, winners of gold in a historic comeback against the U.S. 24 hours earlier, left a note of encouragement in the Team Canada dressing room, and the avalanche of gold medals since Wednesday undoubtedly steeled the collective will of the Canadians that the semifinals would be a bad place to stop their Sochi tournament.
This is something different. After winning gold in 2002, Canada stumbled badly in Turin. Now, after winning gold in Vancouver, there has been no stumble, although there was a Latvian scare, to be sure.
Since NHLers started participating in the Olympics, no country has won consecutive gold medals. Now, Canada has a shot at winning back-to-back gold medals in men's hockey for the first time since the triumph in at the 1948 St. Moritz Games was followed up by gold in Oslo four years later.
Six decades have passed. Time for another back-to-backer, wouldn't you say?
