Jordan Staal, Teuvo Teravainen, Dougie Hamilton and Ryan Dzingel each found the back of the net in the first period for the Hurricanes, who improved to 4-0-0 on the season. Early in the middle frame, Dzingel scored again to push the lead to 5-0. Shortly after, MacKenzie Weegar got Florida on the board at 5-1.
"Some of those goals were self-inflicted," Quenneville said of the first period. "Whether we're not ready to play, you get down one or two [goals] at home in the first period it's going to hurt a bit… I didn't like our response. We got going a little too late in the game when the game was over."
In the third period, Keith Yandle and Evgenii Dadonov each converted on the power play to cut Florida's deficit down to 5-3. With the goaltender pulled and time winding down in regulation, the Panthers had several good looks but were unable to beat former Panthers goalie James Reimer, who made 47 saves.
With just over a minute left in the game, Sebastian Aho put the Hurricanes up 6-3 with an empty netter.
"Of course the start wasn't what we expected," Panthers captain Aleksander Barkov said. "We can't come here and expect we're going to play well all the time. It doesn't matter how we approach the game, we're not going to play well if we don't work hard enough.
"It starts with myself, by not being ready at the beginning of the game. I know it's the beginning of the season, but you have to be ready right from the start. We're going to learn from this, for sure, and keep moving forward."
After posting 10 shots in the first period, the Panthers registered 40 over the final two frames.
"I think we came out a little flat," Panthers defenseman Keith Yandle said. "I don't know if we weren't ready to start or what it was, but we showed a lot of pride in working to come back. It's one of those things that's too little too late. When you give up four in the first period, it's tough to battle back."
