I think both teams have legitimate cause for concern.
The US has been playing at a very high level and that simply cannot go on forever. Ron Wilson simply must energize its team, which had originally booked return flights for this morning as they didn't expect to get this far.
On defense they need to continue to make sacrifices by blocking shots. Miller has been so good because only around half of opponents shots are getting to him--they blocked 26 against Canada the last time around.
On offense they have to just shoot the ****ing puck. Make Luongo have to work. Shoot enough, and some will get through.
An early goal will help take the crowd out of the game.
Canada has to play better defense. Their goalies are not playing that hot in this tournament and you can't rely on them. Against the US the last time they allowed just 23 shots on goal and four were let in by the goalie (one was empty net). Against Germany in the bracket round they allowed 23 and let 2 in. Against Russia, 3 goals on 28 shots. Against Slovakia, 2 on 21. Statistically they cannot keep up with the US, which allow far more shots on goal and have far fewer goals against on average. They should try to trim off four or five shots.
While the US has to simply shoot the puck more, Canada needs to focus on quality shots. They waste far too many shots on low-probability tries. It won't work against Ryan Miller. They not only need to draw Miller out of position with precision passing (something Canada can do extremely well) but they also need to draw defenders out of position because of USA's shot-blocking mentality.
They've got the crowd on their side and need to keep them in it with an aggressive physical game. Team Canada is bigger and meaner than Team USA and they need to use the intimidation factor.
