Well I am sure both media sites are trying to create something out of nothing here. Yakupov made some comments and Cherry replied to it thats all.
The game will for sure be decided by the better defensive team, Canada's lockout line was insane against Germany but the first true test will be against the USA, if they beat this team easily too then Russia is going to have a very hard time overcoming the Canadians.
Gauging by their performances against Sweden and Germany, Can and USA seem to be on very similar paths. USA vs Swe (3-2 OT), Can vs Swe (2-1 SO), Can vs Ger (9-3), USA vs Ger (8-0). We'll see how that pans out when they hit the same ice.
