Missed opportunities are a dime a dozen in sports, but the Rangers’ failure to make it out of the first round of the playoffs — equipped the way they were — just may be one of the most disappointing whiffs in recent memory.

Such was a result of their 4-0 loss to the no-quit Devils in Game 7 Monday night at Prudential Center, where the Rangers were outplayed in every sense of the word and were shut out for the second time in this series.

The talent assembled on this team will haunt the Rangers organization forever.

Hockey fans will look back at this roster and think: “How did that team not win the Stanley Cup?”

“Talent doesn’t mean a thing,” Rangers head coach Gerard Gallant said sharply after the loss. “It’s great to have talent, but you’ve got to play together and work together. Obviously, the four games that we lost, we had two goals. That’s the bottom line. You’re not going to win if you get two goals in four games.

“I love to have talent, but you love to have work ethic and more forecheck and stuff like that. We just didn’t get it done.”

The Rangers who dominated in Games 1 and 2 for a 2-0 series lead never fully returned.

They got comfortable, fed into the Devils’ ballooning confidence and allowed their opponents to waltz back into the series and ultimately seize the opportunity that was in front of them.

Even if it took two tries to set it up, the Devils earned their second-round matchup with the Hurricanes, which will begin Wednesday in Raleigh.

The Rangers just did not do enough with what they had.

In fact, in Games 5 and 7 — two of the three most pivotal moments of the series — they posted zeroes.

Rangers president and general manager Chris Drury brought in two aces, Patrick Kane and Vladimir Tarasenko, in addition to strong supporting players Niko Mikkola and Tyler Motte.

These pieces were added to an already-loaded lineup that featured some of the most highly skilled skaters in the NHL, with a lights-out goaltender, Igor Shesterkin, as the last line of defense.

The Rangers simply fumbled a winning hand.

“Every year you have that same feeling, you don’t know how many kicks at the can you’re going to get,” captain Jacob Trouba said. “Tomorrow’s never given, especially in this league. Feels like we let an opportunity slip away.”

The Devils had nothing to lose, and the Rangers had everything to lose.

It was apparent in Lindy Ruff’s pregame press conference, in which the Devils head coach was loose. Carefree, you could say.

Jack Hughes even went as far to say the Devils were playing with house money.

So the Devils naturally got off to another commanding start, hammering the Rangers in their zone for a bulk of the first period.

Just like in Game 6, however, they struggled to stay disciplined early and were called for three penalties in the opening 20 minutes alone before tightening up as the night progressed.

It hardly mattered, as the Rangers failed to get much going on any of their four power plays.

Getting severely out-hustled during five-on-five play, the Rangers’ inability to capitalize with the man-advantage proved to be a difference-maker.

Shesterkin, who finished with 20 saves, kept the game scoreless for as long as he could.

A shorthanded goal from Michael McLeod and a hard-nosed play from Tomas Tatar in the second period broke the seal, and the Rangers were never able to muster a response.

Erik Haula then netted a dagger in the third period, which got The Rock absolutely rocking, before Jesper Bratt’s empty-netter sealed the Rangers’ fate.

Instead of glory, there will be questions about how it all went wrong for this Rangers team.

Was getting Kane, who the Rangers moved mountains to obtain only for Kane to clearly labor in his short New York tenure, a mistake?

Should the club have focused on adding more grit instead of skill?

How did Artemi Panarin and Mika Zibanejad combine for a single goal?

How does a lineup with such firepower get blanked twice in a single series?

All that can be asked right now, however, is where do the Rangers go from here?

They already took care of one of their three key restricted free agents by signing Filip Chytil before the playoffs, but what is next for K’Andre Miller and Alexis Lafreniere?

Negotiations are not expected to be easy with Miller, while there is no track record from Lafreniere’s agent to go off of.

Do the Rangers even want to hold on to Lafreniere, who not only didn’t record a single point in this series but had another mediocre season?

Plus, it’s likely that the team will be right back where it started before this year’s trade deadline: Without two top-six right wingers.

For now, the members of this star-studded team will be cleaning out their lockers this week instead of boarding a plane to Raleigh.

The Devils’ rebellion continues.

What a waste.
