MONTREAL — An extra day of rest between Stanley Cup Final games might ease forward Josh Anderson and the Montreal Canadiens’ lingering disappointment of falling behind 3-0 to the defending champion Tampa Bay Lightning.

It won’t, however, change the daunting challenge they face in being pushed to the brink of elimination with Game 4 at Montreal on Monday.

It’s win or stay home for the rest of the summer.

“We’ve got nothing to lose at this point,” Anderson said Sunday. “Everyone’s going to be ready for tomorrow night. We’re not finished yet.”

Mathematically, no.

But that might be all the Canadiens have going for them in a series in which they’ve yet to hold a lead, been outscored a combined 14-5, and coming off a rough 6-3 loss Friday in the first Cup Final game played in Montreal in 28 years.

The Lightning are spurred by the objective of seeking to join the 2016 and ‘17 Pittsburgh Penguins as just the second to win consecutive titles since the NHL’s salary-cap era began in 2005. Tampa Bay is also in position to complete the 21st 4-0 sweep in final history — the first since Detroit against Washington in 1998.

The Lightning, who beat Dallas in six games to win the franchise’s second title last year, are a playoff experienced team in making their third final appearance since losing in six games to Chicago in 2015.

And Tampa Bay hasn’t forgotten the sting of how 2019 ended, when the Presidents’ Trophy winners were embarrassed when they were swept by Columbus in the first round. Anderson played for the Blue Jackets that year and knows the Lightning well, saying, “They’ve grown as a team” since then.

“When you’ve gone through some tough times, to be honest, you try to build on them,” Lightning coach Jon Cooper said. “It feels good to go through that, and when you start tasting success, you don’t want to go backward. You just want more. It’s like an addiction. These guys are feeling it right now, and hopefully we can keep it together and finish this one off.”

The Canadiens have the uphill climb of attempting to become just the fifth team — and second in the Cup Final — to rally from a 3-0 series deficit. And only five other times has a team lost the first three games of a series before rallying to simply force a Game 7.

The degree of difficulty is that much steeper against Tampa Bay, which has cashed in on various Montreal miscues.

“Errors in execution. It’s not much more complicated than that,” interim coach Dominique Ducharme said. “It seems like every time we make a mistake, we pay cash.”

He didn’t specify Canadian or U.S. dollars.

What the Canadiens did so successfully in capitalizing on other opponents’ mistakes in their deepest playoff run in 28 years is now being consistently done to them.
