Last season, the Lightning set their records for wins (54) and points (113) before a seven-game loss to the Washington Capitals in the Eastern Conference Final.
"In the role I am in, I am 100 percent committed this year, and we are going to do everything we can to win and have as successful a season as possible," he said. "Beyond this year, I don't have an answer."
BriseBois, 41, becomes the third-youngest general manager in the NHL behind John Chayka (Arizona Coyotes, 29) and Kyle Dubas (Toronto Maple Leafs, 32). BriseBois was named Lightning assistant GM and GM of their American Hockey League affiliate in Norfolk on July 16, 2010. Norfolk won the Calder Cup in 2012, and Syracuse, the Lightning's current AHL affiliate, made the Calder Cup Finals in 2013 and 2017. BriseBois said he will remain Crunch GM, at least to start the season.
"The reality is, in terms of being the guy and the decision-maker, I've been doing that for 12 years at the minor league level," BriseBois said. "The amount of autonomy I had in overseeing our player development both in Montreal for four years and my eight years here with Steve, I pretty much had carte blanche to run the program. So with regards to being the guy that has to make the decision, I'm comfortable with that, I'm used to that.
"I'm well surrounded by the people that we have in our organization and I'm excited about that, the fact that I'll be able to count on really good people that are good at what they do. I think the biggest difference is there's a lot more scrutiny at the NHL level than there is at the AHL level. That really is the most important difference, and time will tell how I handle that."

He was executive director for Canada when it won the gold medal at the 2014 Sochi Olympics,
"He's even a better leader and general manager than people give him credit for," BriseBois said. "That's why it's really important to me that he stay on board and kind of be my sounding board going forward or for at least this year. And we'll revisit that at the end of the season. Hopefully he'll stay for more than one year."
