I do also think that Czechs are the threat number one to Russia, because a) they play better than any other team here, maybe levelling Russians,

they lost to Russia already and need no more motivation if they meet again.
Also USA is dangerous. I know Canada beat them, but hardly, and occasinally, being worse in the game, oh, yes, I forgot, the reason was that they did not need to play well, if was not playoff, on the other hand, Russians, of course, did need as if it were playoff and showed their best against Czechs, LOL

Terrific logic you have, guys
