This is nothing new. The Finns have given the Americans and the Canucks fits on more than one occasion over the years. Clog up the middle, rely on stellar goal tending and look for a few breaks. The long and the short of it is that teams like Switzerland, Finland and Sweden keep it close on occasion based more than anything on stellar tending (Martin, Raty, Schelling). This is no different than the "Great Wall of China" leading the Chinese to the medal rounds in the 90's. The reality is that teams like Sweden, Finland, Russia etc, have a few great players, but no depth to challenge the two big teams. Play Canada or USA ten times and they may win one game.
Don't get me wrong, for the good of the game, would like teams like Sweden, Finland, Russia etc to be able to challenge more on a consistent basis. While the depth of number of teams behind the top two is greater today than four years ago, the gap to the top two has not really closed all that much. JMO.
