The Montreal Canadiens lost a heart-breaking Game 1 in double overtime to the Tampa Bay Lightning Friday night at the Bell Centre.

But the play should have been whistled dead before Lightning winger Nikita Kucherov scored 2:06 into the period to give a 2-1 victory to the Lightning. 

Shortly after Kucherov's goal, replays revealed Lightning centre Valtteri Filppula was off-side as the Lightning entered the Canadiens' end.

The missed call is a moot point now, but that didn't stop Canadiens head coach Michel Therrien from voicing his frustration to reporters following the game. 

Therrien lamented the non-call while celebrating his team's effort. He emphasized that an off-side is not a judgment call the same way that a penalty would be. 

Therrien's comments on the controversial call begin at 1:06 of the video below:
