In the playoffs, emotions run high, and fans, as well as players on the ice, become much more sensitive.
It's true that it's very frustrating when you feel like your nemesis is refereeing the game. As a Canadiens fan, when I learn that Chris Lee will be there, I know the players are facing two opponents.
Nevertheless, I don't believe it's colluded with the guy in charge. Not in 2024. It's just a coincidence, but referees are professionals, and I don't believe they show favoritism.
