America as the underdog against Canada? It happened tonight

I was thinking about it while watching CANADA versus the USA in men's Olympic hockey tonight.
There are few instances when America can be considered the UNDERDOG in relation to our neighbors to the north.
Economy? Nope.
Cultural influence? Nope.
Any sport besides hockey (and probably curling)? Nope.
So, it was odd to think of the team in red, white and blue as David to a Canadian Goliath.
Both teams sported players from the NATIONAL HOCKEY LEAGUE -- teammates faced teammates, line mates faced line mates and even roommates faced roommates -- albeit wearing differing national team sweaters. Because of the NHL presence, the gap in talent wasn't that great.
Still, the Americans were 2-10 with three ties all-time against Canada, and posted five losses and a draw since a 2-1 win in the 1960 Squaw Valley Games.
It was an upset, then, when Brian Rafalski scored twice tonight and the USA beat Canada, 5-3.
