During the first game against Iceland the team does the "flying v" but when they get knocked down, the announcer says, "Oh, it's a 4 on none break away," but there it was really a 5 on none! (What were the editors thinking?!?!)
In hockey, when there's a breakaway, you subtract the goalie from the numbers. So a 5-on-1 is a 4-on-none, a 3-on-one is a two-on-none, etc. The announcer was correct.
