Can't go by W's and L's, because too many games are too close in score too often(I believe soccer is based on points as well, for the same reason). Can't tie in the NBA or MLB, and ties are rare in the NFL, but those league have different values for scores. You have 1, 2, and 3 point shots in the NBA, can score anywhere from 1-4 runs on a single hit in baseball, and the NFL has 1, 2, 3, and 6pt scores. How often are any games in those leagues tied? In the NHL, every goal has a value of 1. Doesn't matter how you score, where you score, or when you score, every goal is worth 1. The 76-77 Canadiens, when there was no OT at all, with a goal differential of +216, had more ties than losses.
