If a team loses in overtime or a shootout, that is not a loss. It is an overtime loss. If the Bruins last six games are three losses, then a win, then two overtime losses, that is not a record of five losses and one win in the last six games.
What's the difference? Well, you don't actually lose anything with an overtime loss. You get one point. Your record -- as a percentage -- remains what it was. You don't sink, you don't swim: you tread water. It is exactly like what used to be a tie, in all respects. They call it an "overtime loss," but they treat it like a tie.
You'd think ESPN would get that sort of thing correct, since they are supposedly experts on sports.
