NEW YORK — Having already experienced both sizzle and stumble, it has become clear that this could well be a season determined in the margins for the Miami Heat.

As in the margin between yet another trip to the play-in round — a fourth in a row — or something more substantive.

As in the margin of one more 3-pointer or one more rebound, elements that already have determined so many games this season for Erik Spoelstra’s team.

As in the margin of adding one more 3-point shooter or one more rebounder.

As in the margin of what to do about this entire Terry Rozier salary-cap dilemma that NBA Commissioner Adam Silver effectively put the issue back in the Heat’s hands during his media session at the the NBA Cup, when he essentially said the league would rule on potential Rozier salary-cap machinations if the need arose.

It could arise in one of two ways:

— The Heat attempt to waive Rozier by that Jan. 7 guarantee deadline in order to free his non-guaranteed money, money which would be enough to replace him on the roster with a player at a pro-rated share of the veteran minimum and still keep the Heat below the punitive luxury tax.

— The Heat keep Rozier’s money on the books beyond Jan. 7, with an eye on including his entire $26.6 million 2025-26 salary as a cap-matching tool in a major trade by the Feb. 5 NBA trading deadline.

Understand, none of that also could happen, with it as simple as the Heat regain their early-season mojo, ride it out, allow Rozier’s contract to expire at season’s end, and then see if his salary eventually winds up being recouped if he is ruled ineligible because of the FBI gambling investigation.

That latter approach in many ways would be un-Heat-like, a team that has been as crafty, clever and creative as few others when it comes to maximizing cap twists and turns.

Which brings it back to the debate of margins or massive.

On one hand, the notion of Pat Riley and whales and swings for the fences is you think big, bigger, biggest, amass assets for singular all-in moves, such as the Shaquille O’Neal trade in 2004, the cap space stored for the 2010 free-agency haul with LeBron James, Chris Bosh and Dwyane Wade, or even the assets cobbled together for Jimmy Butler in 2019.

In that regard, Rozier’s expiring salary arguably should be retained intact, until the trade deadline, to see if something big, something requiring $26.6 million in cap ballast can be utilized.

Recall, when the Heat initially acquired Kyle Lowry in 2021 free agency, the transaction was completed with a tacit acceptance that Lowry likely would be moved by the final year of that three-year, $85 million contract, a cap asset to put into play for future gain.

That final year was utilized to acquire Rozier in January 2024.

Say what you want about the Rozier deal now, but few were questioning at the time moving off Lowry’s money and languid play for Rozier (now, the tossing in of a still-owed first-round pick is another story).

To that end, if the Heat now can turn all of Rozier’s contract-ending salary into something tangible (Hello, Giannis?), then a previous trade that went sideways can be turned into a course correction for the second time.

Or ...

Or, because this team, for better or worse, for play-in or worse, lives in the moment, by moving off the guaranteed portion of Rozier’s salary by that Jan. 7 deadline, the Heat can nominally upgrade what already is in place by taking Rozier’s non-guaranteed $1.6 million and turning it into another roster component. (Whether the Heat can recoup Rozier’s salary after the fact then would be left to an NBA arbitrator and the courts.)

Yes, a 14th or 15th man rarely turns a season. And if a 14th or 15th man can turn a season, then what exactly is that season?

But then look at this season, or even this past week, with players such as Tyler Herro, Norman Powell, Pelle Larsson and Nikola Jovic were ailing. Jamir Young coming through that door in the loss to the Sacramento Kings certainly wasn’t the answer earlier this month.

Then think about one more Alec Burks 3-pointer in those dying moments in the NBA Cup loss to the Orlando Magic.

Or one more defensive rebound secured to prevent one more Scottie Barnes second-chance point in this past week’s loss to the Toronto Raptors.

On one hand, an argument could be made that another veteran brought in means another moment of playing time lost for a prospect, be it Larsson or Kel’el Ware or perhaps, now, even Kasparas Jakucionis.

But then look at the standings, at the fine line between No. 3 and No. 9 in the East.

The margins matter.

So does the idle Rozier money sitting on the Heat’s cap.

It is time to make a decision.

Terry Rozier is in the Heat’s past tense, likely the NBA’s past tense.

Make the NBA act.

Force the league’s hand.

More is needed, as the stumble after the sizzle has shown.
