Should be a very exciting game. Russia is always dangerous and they're in a perfect position to strike after having a couple of bad games (especially against Denmark) in the tournament. They always play well against US too.
US is the stronger team with better game breakers though, and they've faced adversity, 0 goals on 40 something shots against Sweden and a close 2-1 win against Canada. But they've gotten better as the tournament went on and are firing on all cylinders right now.
Could easily be a 4-4 type of game.
It just feels like i've seen this before, Russia struggling with smaller country in the QF, then they climb back and win building up the feeling that they can overcome tough situations and then they pull out 7 goals out of their ***** against one of the best teams in the tournament and come away with the "upset". Not necessarily the case this time around, but they can put up a solid fight for sure.
