It was a referee call. I’m not familiar enough with hockey rules to know if it was legit.
The US goal was out of alignment. Nit-pick rule, but all teams agreed to them prior to the Olympics. Russia would have been the first to have cried fowl were the situation reversed. Oshi made a great shot for the US win!
In my opinion the Russians actually did get hosed by that call.
The goal was disallowed because the net had come off of it’s moorings. However, in replays you can clearly see that US goaltender Jonathan Quick is the one who ran into it and dislodged it in the first place. Whether that was deliberate or not, who knows. But he wasted no time pointing at it and making a big deal after Russia had put the puck in the net.
On the other hand it is the job of the officials to notice when the net comes off and to stop play.
It was a fantastic game and I’m sorry that a stupid controversy has tainted it.
