The Luka Doncic Era May Be Ending in Dallas, but Cooper Flagg Isn’t Replacing Him—He’s Creating Something Entirely New

Dallas has spent the last six years orbiting around Luka Dončić. The Slovenian superstar brought hope, highlights, and heavy expectations to the Mavericks franchise from the moment he stepped onto an NBA court. He’s dazzled fans, frustrated defenders, and pulled a mediocre supporting cast further than it probably deserved to go. But now, in the summer of 2025, a whisper has grown into a roar: the Luka era might be nearing its end in Dallas.

Enter Cooper Flagg.

No, he’s not here to replace Luka Dončić. That would be a mistake in framing and an insult to both players. Flagg, the No. 1 overall pick in the 2025 NBA Draft and one of the most hyped prospects since LeBron James, isn’t trying to fill Luka’s shoes. He’s lacing up his own — and he’s here to blaze a completely different trail.

The Mavericks find themselves on the edge of a cultural and competitive transition. The dynamic between Dončić and the front office has cooled, insiders suggest. With two years remaining on his deal and a player option looming, the possibility of a trade has become more than a hypothetical. Especially with rumors swirling around Miami, Los Angeles, and even Boston expressing interest.

Dallas didn’t draft Flagg as an answer to Dončić’s departure. They drafted him because he represents a new foundation, one built less around heliocentric offense and more around versatility, defense, and winning habits that transcend box scores. He’s not a successor — he’s a revolution.

Flagg doesn’t talk like a savior. “I’m just here to work,” he said after his introductory press conference. “There’s a lot I need to earn. Nothing’s given.” The 6-foot-9 Maine native brings not just elite athleticism and defensive instincts, but a mindset that has already endeared him to teammates and coaches. “He just gets it,” said head coach Jason Kidd. “He’s locked in, he wants to be coached hard, and he wants to win. That’s a rare combination at 19.”

What makes Flagg’s presence so intriguing is the contrast he provides to the basketball world Dallas has inhabited since 2018. Luka, for all his brilliance, thrives in controlling the offense, dictating tempo, and dominating usage. It’s beautiful when it works, but in the playoffs — where defensive schemes tighten and legs grow weary — it can be burdensome. Flagg, meanwhile, doesn’t need the ball to impact the game. He defends. He rebounds. He rotates. He talks. He slides into passing lanes. He ignites transition plays. He doesn’t dominate possessions, he connects them.

That connective tissue could become the identity of a new-look Mavericks team.

“I think the city’s ready for it,” said Mavericks assistant GM Keith Grant. “Luka gave us some unforgettable moments — and who knows, maybe we’ll see more. But we also know we need to evolve. We’ve been reactive. It’s time to build a sustainable identity. Cooper is a huge part of that.”

This isn’t a smear campaign against Dončić. He’s still one of the most gifted offensive forces the league has ever seen. But sources close to the team have hinted that the front office is no longer convinced he’s the centerpiece of a championship roster under the current construction. His relationship with the team hasn’t soured, but it’s clear both parties are eyeing the future with caution.

Flagg provides Dallas with something it hasn’t had since the early Dirk Nowitzki years — a two-way cornerstone who doesn’t need to monopolize the game to influence it. He’s the rare kind of player who makes others better not by feeding them the ball, but by playing the kind of basketball that’s contagious. “He’s like a young Kawhi mixed with Scottie Pippen,” said one Western Conference scout. “Long arms, fast hands, elite footwork. But mentally, he’s already 25.”

He’s not without flaws. His jumper is still streaky. His offensive assertiveness comes and goes. But the Mavericks aren’t rushing him. Instead, they’re building an ecosystem that lets him grow into the player they believe he can become — a franchise pillar with fewer stylistic dependencies than Dončić, and more defensive reliability.

This summer, Dallas moved quietly but purposefully. They added veterans who don’t need the ball — smart role players like Dean Wade and Delon Wright. They extended Derrick Lively II, believing he and Flagg can anchor one of the best young defensive frontcourts in the league. And they’ve made it known: they won’t trade Flagg under any circumstances. The only question left is whether Luka Dončić wants to be part of the next chapter.

Publicly, Dončić has said the right things. “Cooper’s a great kid,” he said during a June interview with Marca. “He works hard, plays defense, and wants to win. That’s what we need.” But those close to Dončić say he’s frustrated — not with Flagg, but with the franchise’s direction. He wanted win-now veterans, not another development project. The Mavericks, in contrast, are trying to have it both ways — win now with Luka while grooming Flagg as the face of tomorrow.

At some point, they may have to choose.

And that time may come sooner than anyone expected.

League executives have floated the idea that Dallas could move Dončić before the trade deadline — not because they have to, but because the optics of letting him walk for nothing would be disastrous. If Luka expresses doubt about re-signing, the Mavericks might pull the trigger on a blockbuster deal that fetches them multiple picks, players, and flexibility. Miami, desperate for a new star, is lurking. Boston, with assets to burn, has checked in. The Lakers, of course, are the wildcard.

In a way, Cooper Flagg has accelerated the timeline. He didn’t ask for this, but his presence gives Dallas an out — a reason to pivot toward a style of basketball more suited to the modern era: faster, switchier, more team-oriented. With him, they don’t need a singular star to orchestrate every possession. They can hunt mismatches with motion. They can swarm defensively. They can become what they’ve rarely been since 2011 — unpredictable.

And that’s the part Mavericks fans are starting to understand. This isn’t about forgetting Luka. It’s about remembering how championship teams are built. Flagg is a piece you can build around without being restricted by. He unlocks combinations. He accepts coaching. He shares the spotlight.

“He’s not a Luka clone,” Jason Kidd reiterated during Summer League. “He’s something else entirely. And that’s exactly what we needed.”

If the Luka era does end in Dallas — whether this season or next — it will not be remembered as a failure. It will be remembered as a foundation. A time of thrilling offense, unmatched entertainment, and heartbreaking playoff exits. A time when the Mavericks learned what it meant to chase a title — and what they were missing.

And Cooper Flagg? He’s not here to repeat that history.

He’s here to write something entirely different.
