Here's some trivia to impress your friends with.
Hockey's first tied game came on February 11th, 1922 as the Toronto St. Pats and the Ottawa Senators battled to 4-4 overtime deadlock. Clint Benedict was in goal for Ottawa, stopping 63 of 67 shots. John Ross Roach stopped 78 of 82 shots for Toronto.
Prior to that season, all NHL games were decided. The NHL had endless overtime until someone scored a game winning goal. But in the 1922-23 season the NHL opted to go to one 20 minute overtime period. If no one had scored after the extra period, the game would be declared a draw.
