Putting the game out of reach soon after, Anthony Duclair made it 4-2 when, after blocking a shot in the defensive zone, he flew right down the ice, took a pass from Sam Bennett and scored top-shelf at 14:40.
"We never want to get too high or too low," Duclair said of the Panthers, who can never be counted out of any game they're in. "We just want to keep skating and playing our game. We know things will open up. We've got way too much talent, way too much speed and skill, to get shut down the whole game."
Pulling their goaltender in favor of the extra attacker, Chris Kreider pounced on a rebound and scored to make it 4-3 with 45 seconds remaining in regulation, but the Panthers would hold on to secure the win.
Finishing strong, the Cats led 22-14 in shot attempts and 3-1 in goals in the final frame.
"In the third period, we dug deeper," Brunette said of the team's late push. "I liked our third a lot. I thought he came wave after wave, and Bob made some huge saves to keep us in it. We found a way."
With little time to rest, the Panthers will return to the ice to host the rival Lightning on Thursday.
"We just have such a resilient group," Weegar said. "It's the belief."
