From what I know (and what was said when Znarok was disqualified), he was allowed to communicate with an assistant coach using mobile / anything.
So, like, everyone here in Russia knew that he's going to continue talking to them via handsfree, these Swedish guys didn't discover anything new.


Anyway, I don't see what does Znarok's presence or absence has to do with the score / results, it wasn't him who played at the rink.
