Near the start of the movie the hockey players play a game where half are wearing brown and half are wearing white. Watch the brown team. One of the brown players shoots the puck, and the next shot shown is of the brown goalie saving it. I don't know about the USA, but in Canada we shoot on the opposite team's goalie.
No they were just showing scenes, not the whole hockey game...you see brown team shoot then they show another part where the brown goalie had the puck. It was to show action, not the whole game.
