Hockey Night in Canada on the CBC.
The Detroit Red Wings and the Toronto Maple Leafs played one another on Saturday, December 25, 1971. The Leafs won in front of their hometown fans by a score of 5 to 3.
What I learned minutes ago is the National Hockey League has had no Christmas Day games since 1971. (There were six match-ups that night.)
That was forty-seven years ago. Maybe the league should reconsider.
