...3-0 game lead with 10 minutes left. Still, there's no denying that the referees' decision to call a 5-minute major assisted the Sharks on each of their four goals. With no call, it's game over for the Knights. With a 2-minute minor, it's a 3-1 game that plays very differently when the Knights come back to full strength.
I don't disagree with your 30-70 "fault" for the loss; maybe I'd go closer to 50-50 since the referees' call allowed for more than one goal. In other words, the Knights' collapse couldn't have happened without the referees' call.
