The Florida Panthers are one victory away from a second consecutive Stanley Cup championship.

And they are one loss away from a winner-take-all Game 7 in Edmonton.

This is the beauty and the anxiety of a best-of-7 series. Being up 3-2 — as the Panthers are with Saturday night’s 5-2 road triumph — leaves a Florida fan both planning for another championship celebration and superstitiously afraid to do so.

Fans on both sides of the border can agree on this: Festooned by three overtime games, it’s been quite a sensational Final, one not done yet, but nearing its crescendo.

“This has been a pretty incredible one,” said Marchand of this Final. “One of the tightest series I think anyone has ever seen. Most exciting. The talent level. The back and forth. Nerve-wracking at times. We’re all big hockey fans. It makes you realize why you love the game so much and also why this trophy is the hardest one go win.”

Marchand, 37-year-old magician, a Panther for just a few months, was the hero again in Game 5 with his team’s first and third goals.

“I’m just enjoying every moment,” Marchand said afterward. “A special group of guys. I feel like a young guy in the league again. You gotta be in the moment. I think we realize how special a group we have. It’s so difficult on the mind and the body. You gotta embrace the grind.”

Marchand is largely why Florida on Tuesday can win its second Stanley Cup on home ice, after winning its maiden crown last year in a Game 7 at home over Edmonton. A loss Tuesday would mean a Game 7 in Edmonton on Friday.

“We’re in a difficult situation,” admitted Oilers coach Kris Knoblauch. “They’re a good, sound defensive team. They don’t make many mistakes. There should be some credit given to them.”

The Cats led 1-0 in mid-first period (9:12 in) on a Marchand left-handed snap-shot goal off a breakaway from a center-ice faceoff. His fifth Final goal made him only the second to do that in his career since the 1960s. This also was the fourth straight game the Cats have scored first.

But before that first score, the outcome may have been shaped by goaltender Sergei Bobrovsky’s play agains an early Edmonton assault.

“Sergei in the first 10 minutes got tested hard and fast,” said coach Paul Maurice. “On the road if you can keep the building from going crazy that’s big moment.”

Panthers were up 2-0 1:54 before the end of the first — seconds after killing an Edmonton power play — on Sam Bennett’s snap shot off a rebound from a Matthew Tkachuk shot. Bennett’s 15th postseason goal tied an NHL record and his 13th on the road set a new mark.

Florida has outscored Edmonton 11-4 in the first period of this sereis, and Marchand, Bennett and goaltender Sergei Bobrovsky in the first period only feathered their standing as Cats’ favorites for the Conn Smythe trophy as NHL playoff MVP.

The Cats killed a third straight Oilers power play in the second, albeit with good fortune, as a Connor McDavid shot clanged off the goalpost.

Marchand scored again for a 3-1 lead five minutes into the third period with a brilliant back and forth slalom past Oilers defenseman Jake Walman that all but left Walman corkscrewed into the ice. Marchand thus became the first NHL player since 1988 with six goals in a Stanley Cup Final — the Conn Smythe all but his.

“Just tried to get inside and get a puck on net,” said Marchand.

“Oh my God! Oh my God! Oh my God!” said a mic’d up Matthew Tkachuk on the bench as Marshand scored again.

“When you need a guy to step up, time and time again he’s there to produce,” said Sam Reinhart of Marchand.

Said coach Paul Maurice of Marchand: “What he can do under duress, in a small area, is world class.”

Edmonton drew within 3-1 on the first goal of the Final from McDavid, briefly enlivening the home crowd.

Briefly.

It was 4-1 shortly thereafter on Reinhart’s finish of a gorgeous pass from Aleksander Barkov, Reinhart’s third straight game with a goal.

Edmonton drew within 4-2 with 3:13 left but hadn’t the time for a miracle. Florida cashed the final goal on an Eetu Lourstarinen empty-netter late.

Florida is now 10-3 in this postseason on the road, outscoring opponents by 61-31. At home the Cats have been only 5-4 by a 28-24 margin, but they’ll have mighty incentive to improve those numbers in Game 6.

“We love the road. Love hearing the crowd against us,” said Bennett.

The Panthers are ready for a fight in this series, always, wherever.

“Everybody is defending, playing hard physically. A lot of fun to play in,” said Carter Verhaeghe. “We like to grind. We have a grindy game.”

Tuesday night, the Stanley Cup trophy will be in the Panthers’ rink.

We’ll see if they can keep it at home.
