Welcome to the sport where a game can start on a Wednesday and end on a Thursday, and nobody complains. This is the NHL postseason, where overtime isn't just a possibility, it's a probability. That's what it's all about. Other sports have the equivalent of overtime, but not like this. NFL overtime games don't last into the wee hours of the morning.
Baseball has extra innings and the possibility of a walk-away home run.
But if the homer comes in the top of the inning, the home team has a chance to answer. No one is allowed a rebuttal in NHL OTs. The goal is in. Game is over. Let the weeping begin.
