Miami Heat Reshape Roster Around Giannis and Klay Thompson

The breeze feels different in Miami now.

Klay Thompson is in South Beach, Giannis Antetokounmpo is the franchise pillar, and the Heat suddenly look and sound like a team that expects to matter again in late May and June.

Thompson arrived after a buyout with the Dallas Mavericks, a late-summer twist that gave Miami one of the most decorated complementary stars of this era. Four rings. A reputation built on big shots and bigger moments. A résumé that still commands respect in any locker room.

“Klay is one of the most iconic players to ever suit up in the NBA,” team president Pat Riley said after Thompson was introduced as a member of the Heat. Riley called him “a four-time battle tested world champion who will fit perfectly into his role as an all-around player at both ends of the court,” adding that while everyone talks about his shooting, “there is so much more he brings to the game. We are blessed that Klay chose the Heat in our quest to challenge for championships.”

That’s the tone in Miami now. Not rebuilding. Not retooling. Challenging.

Heat reshape around Giannis and Klay

Thompson’s arrival gives Antetokounmpo the kind of perimeter threat he hasn’t consistently enjoyed since his Milwaukee days at their peak. Defenses can’t load up on Giannis as freely when one of the best shooters of his generation is waiting on the wing, and the Heat know it.

Miami then moved quickly to add size and depth, bringing in veteran big man Nick Richards. With that, the roster sits at 14 standard contracts, one shy of the maximum. The Heat can leave that 15th spot open. They don’t have to do anything.

But the league can feel it: Miami is hunting one more piece.

The backcourt, in particular, could use another steady hand. That’s where the speculation has exploded.

Ben Simmons talk hits a wall

On paper, Ben Simmons fits a need. A 6-foot-10 playmaker who can defend multiple positions, push tempo, and create easy looks for shooters like Thompson while taking some creation pressure off Giannis? For a minimum deal, that idea will always get a front office’s attention.

Simmons, a three-time All-Star, hasn’t played since the first-round playoff series between the Denver Nuggets and Los Angeles Lakers in 2025. Yet his name has started to circulate again.

Earlier this offseason, Marc J. Spears reported that teams around the league have Simmons on their radar. According to Spears, “several NBA teams have expressed interest in Simmons, who is open to signing a minimum contract.” He added that one source said Simmons already has a non-guaranteed minicamp offer from a Western Conference team.

The comeback is gathering momentum. Just not in Miami.

Heat insider Ira Winderman poured cold water on the idea that Simmons is a realistic option for the Heat right now. In a subscriber-only piece, Winderman stressed that Miami is fiercely protective of the culture it’s building and the hierarchy it has established.

“But also don’t undersell chemistry when it comes to roster construction,” Winderman wrote. Dropping in a star, or former star, such as Thompson is one thing. Sliding a reclamation project into the rotation ahead of players who’ve been grinding for years is something else entirely.

He specifically mentioned Pelle Larsson and Dru Smith as examples of players who have earned their place in the pecking order. For someone like Simmons—or even Victor Oladipo, also referenced by Winderman—to come in and try to re-establish himself, that process could cut against what the Heat are trying to build.

“Again, it’s not about the best 15 players on the standard roster,” Winderman wrote, “it’s about the 15 who fit based on skillset and chemistry.”

That’s the line in the sand. Talent alone won’t be enough to walk into this locker room.

A familiar name for the final spot

So if not Simmons, then who?

Inside the organization, the conversation keeps circling back to a familiar guard: Gabe Vincent.

Vincent spent last season split between the Atlanta Hawks and Los Angeles Lakers, a far cry from the defining playoff runs he helped author in Miami. His game, though—tough, unselfish, defensively locked in—still mirrors what the Heat demand from their guards.

The fit is obvious. Vincent knows the system, knows the expectations, and knows what it means when Riley and Erik Spoelstra talk about “Heat culture” without ever needing it explained.

There are “potentially many reasons” Vincent could find his way back to Miami, as has been reported, but one stands out above the rest: the backing he enjoys from two major power brokers inside the franchise. When decision-makers of that stature are in your corner, a reunion becomes more than a sentimental idea. It becomes a live option.

So the Heat sit at 14 players, their top end transformed by Giannis and Klay, their frontcourt bolstered by Richards, and their final roster spot dangling like bait in front of the rest of the league.

Do they use it on a comeback story? Or on a guard who already knows what it takes to survive a Miami training camp?

That choice will say plenty about what kind of contender the Heat plan to be.
