It does. The team who scores most in the allotted time is the winner. It doesn't apply to individuals though. Knies while playing well, has only 1 assist, but his team have won their 3 games. So, you remember how a team can win a game, but you didn't realize that the players that make that team can impact the game in different way. That is why looking at the box score doesn't really indicate how well a player is playing. For example a defenceman may shut down an opponent and never show up on the box score. ( Admittedly there may be an advance stat for that). Or as another example a player might Hussle and harrass the opponent all game create opportunities by closing down and hounding pucks, like Kines,and not make the scoring tables.
