From an article titled, "Canada might be the loser on seismic NHL day," by the Toronto Star's Bruce Arthur:
It was the Canadiens who registered the most seismic day, though. In Montreal, it’s been an open secret that coach Michel Therrien never meshed with Subban. He would tell people that he believed he could never win a Cup with P.K., and the snubs — some ice-time battles, the triple high-five controversy, giving the captaincy to Max Pacioretty, the way teammates voted for Pacioretty over Subban for the community-minded King Clancy award this year — piled up. GM Marc Bergevin is said to be very close to Therrien; they are not just colleagues, but great friends, down to their families. Bergevin wanted to go to arbitration rather than pay Subban, but was overruled by the owner. Not this time, though.
“Too much personality,” a former Canadiens teammate said. “Saw it firsthand. They hated how much fun he had. The fact that he never sulked and pouted, win or lose, just bugged them, I guess. It made no sense to me, either.”
“I think it was blown out of proportion because of Montreal, the market we’re in,” Bergevin said. “We always look to make a story where there isn’t any. Yes, P.K.’s different, we’re not going to hide that, but there was never an issue, never a problem. I fought with my teammates in practice. It happens all the time.”
Not many believed him.
