Subban had 63 goals and 278 points in 434 games with the Canadiens and won the Norris Trophy in 2013 as the NHL's top defenseman. He helped the Canadiens reach the Eastern Conference Final twice (2010, 2014), but they failed to get out of the third round. The Canadiens did not qualify for the Stanley Cup Playoffs last season.
"It was a dream come true for me to play with the Montreal Canadiens, and the sad thing is that my promise to the city of bringing a Stanley Cup back and wanting to win one, I won't be able to fulfill that promise," Subban said.
Subban said he was not surprised he was traded, even though he felt he did everything he could to prevent it.
"This is a business," he said. "We can't forget that. I've always looked at it that way, that I could very well be traded like anybody else on the team. I just tried to work as hard as I could on the ice to not make that happen."
Subban, perhaps the most popular player on the Canadiens during his time in Montreal, said he wishes there were times teammates got as much attention and credit he did.
"My mentality is I've never been the guy that always has to be the center of attention or has to be the front guy," he said. "I have no problem doing my job and somebody else getting the credit, or the attention being on somebody else. There were times where I probably wish there was more attention on my teammates but I can't help what the media decides to do to write their stories. All I can do is go out there, play the game as hard as I can and take care of what I can control."
