Of the four franchises that comprised the National Hockey League (NHL) at the start of the 1917/18 season, only two remain: the Montreal Canadiens and the Toronto Maple Leafs (originally the Toronto Arenas). In 1919/26, eight new teams joined the league, but only four: the Boston Bruins, Chicago Blackhawks (originally Black Hawks), Detroit Red Wings (originally Cougars) and New York Rangers remain. Who has played the most games vs. another, is anyones guess, Do the Toronto Arena games count?
