Do Knights or Capitals win it all?

History will be made in the Stanley Cup Final — either a franchise first for the Capitals, who have existed for 44 years without a Stanley Cup, or the first title for the Golden Knights, in their inaugural season.

Regardless, the story lines — Can Alex Ovechkin finally hoist the trophy? Will Marc-Andre Fleury win his third in a row? Can an expansion team do the unthinkable? — are endless.

It all begins on Monday (8 p.m. ET, NBC) in Vegas.

Who comes out on top? Let our NHL experts break it down.

Kevin Allen: Capitals in six. The Golden Knights have looked nearly invincible, needing just 15 games to reach the Stanley Cup Final. Marc-Andre Fleury has often looked unbeatable. But there is something to be said for scratching and clawing your way to the Final the way the Capitals did. Washington captain Ovechkin looks as if he’s on a personal quest to deliver his team to the franchise’s first championship. This is a series that will be decided by injuries, breaks and perseverance. It just feels like the Capitals are a team of destiny.

Jimmy Hascup: Capitals in seven. And it will be decided in overtime. This will be the ultimate game in the ultimate series for the NHL. Sure, the Golden Knights will fall short, but their fans will still get to celebrate at home one of the best stories in NHL history. The Capitals aren’t the Capitals without making things interesting in the playoffs. But Ovechkin, unfairly maligned for the Capitals’ playoff disappointments, will score the game winner.

Mike Brehm: Golden Knights in seven. This will a fun series because George McPhee built the Golden Knights and drafted many of the Capitals stars. Even with big scorers on both sides, this will be a low-scoring series because both goalies are playing great. The Golden Knights have been the more consistent playoff team, and that, plus their strong play at home, gives them the edge. Former Capital Nate Schmidt could be a key factor.

Jace Evans: Capitals in six. The Capitals have shown they’re a different group than the Capitals of old by overcoming adversity at every turn these playoffs — from climbing out of a 2-0 hole in their first series against the Blue Jackets to eliminating the Penguins on the road without Nicklas Backstrom to shutting out the Lightning in back-to-back games to win the conference championship. Goalie Braden Holtby is at the top of his game: those shutouts in Games 6 and 7 against the Lightning were his first of the season. Alex Ovechkin and Co. appear to be on a mission to win the franchise’s first Stanley Cup. While they won’t have home-ice advantage, that shouldn’t be a problem: They’re now 8-2 on the road in the postseason.
