The seven-game heater the Rangers carried into Tuesday night’s high-rent district confrontation with Dallas at the Garden has not erased all doubts. The winning streak that began the game before the All-Star break has not quite done that.

But this run is somewhat reminiscent of the 18-4-1 getaway that stamped the Blueshirts as an upper-echelon team in a league without a single great one. There are no 1982 Islanders, 1992 Penguins, 2002 Red Wings or 2013 Blackhawks casting a dark and daunting shadow over the proceedings.

And this stretch surely justifies general manager Chris Drury pushing his chips to the middle of the table as the March 8 trade deadline approaches. The Rangers are not one piece away like the Islanders when they acquired Butch Goring at the 1980 deadline in the most impactful trade in pro sports history. There are imperfections dotting the lineup.

But after surveying the national landscape in which the Blueshirts entered Tuesday fifth overall in the league, two points out of second and five points out of first with the NHL’s fourth-highest winning percentage, Drury and the hierarchy have to be approaching this with a “Why not us?” attitude.

There are different interpretations of what pushing the Rangers’ chips into the middle would mean. It does not mean making a trade equivalent to Tony Amonte for Stephane Matteau and Brian Noonan. It does not mean sacrificing Brennan Othmann. It certainly does not mean forfeiting the rights to Gabe Perreault. It does not mean trading Kaapo Kakko because, well, come on, did that ever make the slightest sense?

But the 2024 first-rounder will be in play, as it certainly should. Anyone in AHL Hartford other than Othmann — and that includes Brett Berard and perhaps Adam Sykora — should be on the table, of course depending on the return to New York. Drury has dispensed draft picks like Pez in exchange for rentals at the last couple of deadlines and that is not a sustainable strategy.

But this is a team that has won once in 84 years that has been built to win now. I am fairly certain everyone at 4 Penn Plaza would like for Igor Shesterkin to be a sure thing, but that is going to have to ride on faith. It is self-explanatory that the Rangers won’t win with average — let alone, subpar — goaltending.

There is this, as well, in advance of this test against a Dallas team that entered Tuesday’s confrontation one point ahead but .003 percentage points behind the Rangers in the overall standings, that there is no Butch Goring on the market.

In a league without a dead-solid perfect team, this is a deadline with more buyers than sellers and without a dead-solid perfect rental to tip the scales. For the most part, the bazaar will feature role players and perhaps goalies.

The Rangers are in need of a right wing to skate with Mika Zibanejad and Chris Kreider. They could surely use an upgrade in the middle of the developing third line featuring Kakko and Will Cuylle on the flanks and Jonny Brodzinski at center. And they could use muscle on the left side of the third defensive pair though the staff may be satisfied to stick with the offense-driving Erik Gustafsson.

The Post has learned that the Blueshirts have identified Seattle center Alex Wennberg as a person of interest to fill that spot in the middle of the third line. The Swede is a pending free agent working on the final year of a free-agent deal he signed with the Kraken in 2021 under which he carries a $4.5 million cap hit.

Wennberg has some size at 6-foot-2, 190 pounds, skates well and would probably play down in the lineup as a third-liner. The Swede, 8-14-22 this season, does not necessarily have the same shooting mentality of Brodzinski playing between straight-liners Kakko and Cuylle, but he has 42 games of playoff experience, skates well and is a no-doubt legit two-way NHL center finishing his 10th year.

The Rangers, we are told, are not alone regarding their interest in Wennberg. The Bruins, who may need a top-six center, have been identified as in the mix. The cost — which would be impacted by Seattle retaining 50 percent of the cap charge that would enable Drury to conduct further business — won’t be cheap. The Blueshirts, though, can’t empty the piggy bank for a third-line center.

Drury will have to be adroit juggling assets over these next two-plus weeks in attempting to transform what has been a very successful regular-season roster brimming with talent over the last three seasons into a playoff lineup with enough fiber and physicality that it can win four series and 16 games. There are holes and there are questions.

But there are holes and questions pretty much everywhere around the East and around the league. The Rangers have been at the top of the division every day since Oct. 24. They won six straight early, they have won seven straight now.

They are one of the league’s best teams and they have played well enough to justify the GM pushing his chips into the middle of the table.
