MIAMI — Thankfully, offseason is about to turn into preseason for the Miami Heat. Perhaps then summer blather will turn into tangible chatter.

When the Heat landed Shaquille O’Neal in the Summer of ’04 and then the Big Three of LeBron James, Dwyane Wade and Chris Bosh in the Summer of ’10, the discourse was of potential possibilities, title talk, championship visions.

Such, seemingly, are the rewards of landing game-changing talent.

And yet this summer, when the Heat added a top-five talent in Giannis Antetokounmpo — a player who on any given night could stand as the best in the NBA — there instead was a discourse of doubt, that the two-time MVP and 10-time All-Star merely had shifted from a Milwaukee Bucks roster of uncertainty to a Heat roster of equal question.

Truth be told, a case could have been made back in June, when the deal was agreed upon, that the questions were legitimate. More was needed for the climb back from the franchise’s first playoff absence in seven seasons.

But there also was an entire offseason ahead.

So as the Heat plan for Tuesday’s start of training camp, how should the offseason be graded?

When it comes to a letter grade, score it as a “P” or, perhaps even a “P+.”

As in P for persistence

As in P for patience.

As in P for possibilities.

What followed the June 22 agreement on the blockbuster deal for Giannis was:

— The drafting of first-round talent (using summer league as the initial evaluation) Ryan Conwell in the second round on June 24.

— The re-signing of 3-point specialist Simone Fontecchio on July 2.

— The signing of Denver Nuggets free agent Tim Hardaway Jr. on July 6.

— A contract extension locking in forward Andrew Wiggins on July 6.

— The signing of Dallas Mavericks buyout free agent Klay Thompson on Aug. 23.

— The signing of Chicago Bulls free agent Nick Richards on Aug. 27.

— A contract extension reached with guard Pelle Larsson on Sept. 22.

And enough flexibility to add up to three veterans at the NBA minimum in coming days, weeks or months, if needed or desired.

By themselves, each of those listed moves in the wake of the agreement to land Antetokounmpo and Bobby Portis from the Bucks back in June hardly shook the transaction Richter scale.

But sometimes it’s not about making a splash after the splash.

Sometimes it’s about persistence.

And patience.

And possibilities.

The initial knock on the Heat’s roster after that June 22 agreement with the Bucks for Giannis was about a lack of spacing on the perimeter.

If the threat of Hardaway, Thompson and even Wiggins, Portis and Davion Mitchell isn’t enough, it’s not for lack of pedigree.

Then it was about a lack of playmaking, as if Antetokounmpo, Bam Adebayo and the assist-to-turnover mastery of Mitchell had suddenly lost such selfless superpowers.

More recently, somehow there was a surfacing of questions about the overall defense, as if Antetokounmpo, Adebayo, Wiggins and Mitchell haven’t stood as superlatives in that regard, with Larsson in the process of creating such a resume of his own.

And, yes, questions remain about shot creation, legitimate questions. But there also is the immediate space to add another salary under the hard cap created by the machinations of the Antetokounmpo trade, with doors to open for two more (if Richards is waived ahead of his opening-night guarantee, and if Myron Gardner is waived after his $500,000 guarantee evaporates).

So, yes, work still to be done.

But also with time to get it done.

Which brings it back to persistence, patience and possibilities.

With Antetokounmpo, there was the patience not to overreact to being rebuffed in the bid for the Bucks big man at February’s NBA trade deadline, to then reload with an offer too good to refuse.

With Hardaway, Thompson and even Richards, there was the patience to wait out the market until the right players could be added at the right price.

And with the extensions with Wiggins and Larsson, the possibilities of adding to the mix in coming offseasons, with future payrolls aligned for moves of substance.

Two years ago, Heat media day at Kaseya Center arrived with Jimmy Butler arriving late in what portended rough waters ahead. He now can be found with the Warriors.

Last year, camp carried the cloud of Tyler Herro’s September foot surgery and the uncertainty of his future as a franchise leading man. He now can be found with the Bucks.

This year, the Heat will arrive at Florida Atlantic University for Tuesday’s opening session of training camp with doubts largely dissipated over the past three months, a roster aligned with Antetokounmpo and Adebayo.

No, not exactly a summer of sizzle after the Antetokounmpo acquisition, but one that showed the value of persistence and patience, as we now get to explore the possibilities.

IN THE LANE

THE IRONY: Among those who struggled most in last season’s shift to the Heat’s “chasing space” offense was Tyler Herro, with the offensive system removing much of the pick-and-roll sets that contributed to his ascension as an elite scorer. The irony is that much of that system on the NBA level was developed with the Memphis Grizzlies under Taylor Jenkins. Now Jenkins is with the Bucks, with visions of installing that system for a roster that includes Herro. “When we transition from defense to offense, how quick can we create an advantage? We want driving layups, cutting layups and catch-and-shoot threes,” Jenkins told Milwaukee’s Journal Sentinel. “Number one we want numbers. Number two, if I see space I’m taking space.” A year ago, Heat coach Erik Spoelstra brought in former Grizzlies assistant coach Noah LaRoche to install such principles, principles that set the Heat offense ablaze, while to a degree leaving Herro in the ashes. Toward the end of last season, with Herro back from his preseason foot surgery, the Heat bent to more of Herro’s game. Now the question in Milwaukee will be whether the Bucks’ bent allows for Herro ball.

FAMILIAR FACES: As teams square away their camp rosters, several players who had put in time with the Heat have surfaced elsewhere. Included in that group is former 2025 camp prospect Dain Dainja, who is going to camp with the Brooklyn Nets after spending last season with the Heat’s G League affiliate, the Sioux Falls Skyforce. While Dainja received an Exhibit 10 contract from the Nets that would include a G League bonus, the Nets would need to acquire his G League rights from the Heat in order to shift him to the Long Island Nets. Elsewhere, former Heat G League players Jon Elmore and Malik Williams have signed camp deals with the San Antonio Spurs. Then there is former Heat big man and two-way player Orlando Robinson going to camp with the Chicago Bulls. In addition, former University of Miami player Norchad Omier is going to camp with the Minnesota Timberwolves.

HERE’S WHY: Returning to his Mind the Game podcast with co-host Steve Nash, LeBron James has shed further light on why he bypassed a Heat reunion in July to instead join the Philadelphia 76ers. Among the reasons is what seems to be a preference to play alongside Joel Embiid instead of Bam Adebayo or Giannis Antetokounmpo. “One of the most important, to be honest, is the big fella, and the only thing he has not done and that’s win a championship,” James said of Embiid. “And I want to try to help him get that first one.” James added, “He has a city on his back. He’s been ‘The Process’ for 10 years, 12 years, however long he’s been there. But I think it’s time we even get you deeper into The Process. And I hope that I can be, kind of, that final little piece that can help him get over the hump.” Also noted was the Tyrese Maxey factor. “When I became a free agent and we decided to let the Lakers know that I wouldn’t be returning, he was one of the first people that was on my line, calling me,” James said.

SEAMLESS FIT: Despite being the only new coach on Erik Spoelstra’s staff, Vin Baker said his shift from Bucks assistant to Heat assistant has felt seamless. “I’ve said this to the people inside the organization and certainly to my family members,” Baker related, “it’s like the one thing that I’ve noticed since I’ve been here for the first month is it’s about family here, everyone, the fact that everyone’s been here together for so long, us former players, Spo’s coached some of the guys on the staff. And so it just feels like a family atmosphere here. Before I felt anything about the culture, I felt like family first. And that’s what’s really awesome. Coming to a new place for the first time on the coaching side of things, after eight years (in Milwaukee), that’s what you want to feel first.” Baker added, “I have a saying that I love, ‘People don’t care what you know until they know that you care.’”

NUMBER

2. Players currently under contract to the Heat three seasons from now, with Nikola Jovic ($16.2 million) and Pelle Larsson ($15.5 million) the only salaries on the Heat’s books for 2029-30. That should change on Jan. 6, when Giannis Antetokounmpo becomes trade-eligible, and possibly sooner if Davion Mitchell agrees to an extension.
