From strutting out of the Prudential Center to slinking out of it, the Rangers have been turned upside down by the Devils.

Not even a fraction of the Rangers team that came into the same building just last week and put forth two of their best performances of the season showed up in their series-swinging 4-0 loss to the Devils in Game 5 Thursday night.

The Broadway Blueshirts who danced around and had their way with the Devils in Games 1 and 2 in Newark were shutout by a rookie goaltender in the most pivotal contest of the season and are now facing elimination Saturday night at the Garden.

Oh, how the mighty Rangers are falling, while the timid Devils have awakened.

The Rangers have steadily lost themselves as this series has progressed.

The Devils, on the other hand, have gotten the hang of this playoffs thing.

What was two straight victories of the Rangers coming up with every loose puck has turned into three consecutive losses in which the Devils have shown way more fight.

It has culminated in the Rangers reverting to their disjointed phase they endured when Patrick Kane and Vladimir Tarasenko first joined the club.

There was simply no flow to the Rangers game Thursday night.

The star power of this Rangers lineup has fizzled.

Mika Zibanejad and Artemi Panarin went another game without a goal.

Kane continued to be bodied off the puck, while Tarasenko has significantly dropped off after a strong start to the series.

The Kid Line can’t find its groove below the hash marks. The power play is on a 0-for-13 skid.

Even goalie Igor Shesterkin, who finished with 36 saves in the loss, launched a puck down the ice to put a shot on goal at one point in the second period to try and get something going for the Rangers,

It’s apparent just how much more confidence the Devils are skating with after powering back from a 2-0 series deficit.

They were decisive with the puck and playing a cohesive game.

The Devils, who made some more lineup tweaks, even looked taller on the ice since they seemed to be standing up straighter.

After scoring the first goal for the second straight game, when Ondrej Palat’s shot off a loose rebound chipped off Adam Fox’s stick and over Shesterkin just 39 seconds into the opening frame, it set the tone for what eventually became the Devils most complete game of the series.

Not only did they hold the Rangers off the scoreboard, but they made it difficult for them in all three zones.

Erik Haula scored twice, once on the power play in the second period and the other on an empty-net to cap the scoring in the third.

When the Rangers earned one of their two power plays on the night later in the frame, Panarin couldn’t handle a pass and it sprung the Devils on a two-on-one rush the other way. Dawson Mercer buried it for the 3-0 lead.

The series has been inverted.

The Devils have the upper hand.

The Rangers are one loss away from an early exit from the playoffs.
