"Sometimes that's just the way it works," Marchand said. "Different teams, different players, goalies that feel good against certain teams and over time that confidence grows and builds. He always plays very well.
"I don't think it's even just Florida; he plays great every night. He's been extremely good this year and he gives us an opportunity to win every game. It happens to work out that he plays good here."
Marchand, who had his first two-goal game since the season opener against the Columbus Blue Jackets, scored a shorthanded goal in the first period and on the power play in the second.
"That's the kind of guy he is," Bruins coach Claude Julien said. "He can score in all situations. Tonight he was having a good night."
The Panthers, who placed forward Nick Bjugstad on injured reserve after he sustained a lower-body injury against the Nashville Predators on Friday, lost forward Greg McKegg to an upper-body injury in the second period.
"Our guys are giving it every single thing they have and were working hard tonight," Panthers coach Tom Rowe said. "We played a very good team tonight, had their entire lineup, the first time they were healthy all year. Our guys accounted well for themselves from an effort standpoint. We just made some systems mistakes and they took advantage of them."
