Anything can happen in a Game 7 and you knew that even before Florida took out the record-setting B’s in Boston and the terrible-two’s Kraken deposed the defending champion Avalanche in Denver on Sunday night, one after the other, didn’t you?

And there are those times that everything can happen, as it did at the Garden in 1994 when the Rangers and Devils hooked up in an historic decider of an epochal series, 29 years before the clubs would stage a reprise Monday at the Rock.

The scenario was different, of course, Game 7 of the conference finals then as opposed to Game 7 of the first round now. The Rangers, on a famous 54-year drought and the Presidents’ Trophy winners, had survived the Guaranteed Game 6 at the Meadowlands on soothsayer Mark Messier’s hat trick.

The Devils, second overall to the Rangers by six points during the regular season, had only 48 hours to mend after allowing their 2-0 lead in Game 6 to be swept away by No. 11 and Mike Richter.

“We just gave that game away,” Claude Lemieux told The Post by phone on Sunday when asked for his recollections. “I was angry about that but once it was over, we couldn’t do anything about it.

“You have to have short-term memory in the playoffs and be able to block out the past. I don’t think there was any kind of hangover. We knew we had outplayed them for a lot of the series, so we were pretty positive. I just felt, ‘So what about Game 6? We’ll get the next one. We’ll beat them at home.”

That represented the second Game 7 in three years between the clubs. The Rangers had won the Presidents’ Trophy in Messier’s first year on Broadway. Roger Neilson was behind the bench. The Devils had finished fourth in the division with Tom McVie as the coach.

The end of the season and the start of the playoffs were delayed by the only players’ strike in NHL history that began April 1 and lasted 10 days. The dividing line between the regular season and the playoffs was thus blurred even more than usual.

Even more than a club with the 17th-overall best record knocking out the team with the most wins and points in NHL history as happened on Boston’s Sunday Bloody Sunday.

“I know there was that fight at the end of Game 6 but I don’t remember much about the ’92 series,” said Lemieux, who had come to New Jersey from Montreal during the summer of 1990. “It was my second playoffs with the Devils, we were still a fragile team.

“We competed hard. I don’t remember anything about Game 7. What was the score?”

The score was 8-4.

“No wonder I don’t remember,” said the winger.

Everyone remembers the score of Game 7 in 1994. It was 2-1 in double overtime when a deadline acquisition named Stephane Matteau scored in front with bodies around and in Martin Brodeur’s crease.

And everyone also remembers that the score had been 1-0 until 7.7 seconds remained in the third period after Brian Leetch had scored a spectacular goal in the second period to give the Blueshirts the lead.

“Zelepukin, right?” Lemieux asked.

Yes, it had been Valeri Zelepukin in front off a pass from, yes, Lemieux following a draw in the left wing circle on which Bernie Nicholls had been beaten by Messier.

“It was a set play,” said New Jersey’s No. 22, a four-time Cup winner who is one of the great money players in NHL history. “I told Bernie to lose it clean and that I would come up with the puck and that’s what happened.

“And then we lose on a goal that goes off a player’s toe. Bernie scored 475 goals and had an open net in the first overtime but missed it. What are you going to do?”

Lemieux did not mention that the offending foot had belonged to Slava Fetisov while Jim Dowd was occupied on the other side of the crease with Esa Tikkanen.

The Rangers had home ice in that one. The Devils owned home ice in this one on Monday. The ’94 Devils had previously won two at the Garden. The ’23 Blueshirts had already won two at the Rock.

“I’m not a big believer in home-ice advantage in the playoffs, especially for a Rangers-Devils series and even more for a Game 7 in New Jersey,” Lemieux said. “There are so many Ranger fans there, for me, an emotional guy who feeds off the energy in the building, that’s hard.

“I’d rather play in their barn.”

Monday, it was in the Devils’ barn. Monday, the Devils needed short-term memory following 5-2 for the Rangers in Game 6.

Monday was a Game 7 the Battle of the Hudson has been awaiting for 29 years.
