Colorado tied the 1976-77 Montreal Canadiens, the 1983-84 Edmonton Oilers, and the 1995-96 Detroit Red Wings for combined regular season and playoff victories in one season.
The NHL rulebook provides a lot of discretion for officials in calling or not calling too many men penalties. The question's if this situation escalated to the must-call point. (And no, the game sheet doesn't prove that.)
Colorado became just the third team to record a Stanley Cup Final shutout by seven goals or more, and also just the third team to score three or more goals in the first period of the first two games of a Stanley Cup Final.
