# Cooper Flagg Turns Heads With Announcement on Monday
**By Alex Rivera, Athlon Sports NBA Insider**
*November 28, 2025 – Dallas, TX*
In a move that’s sending shockwaves through the NBA world, Dallas Mavericks rookie sensation Cooper Flagg dropped a bombshell announcement on Monday afternoon that has fans, analysts, and front offices buzzing like never before. The 18-year-old phenom, already turning heads with his electrifying play on the court, revealed via a heartfelt video on his social media channels that he’s committing to a multi-year extension with the Mavericks—forgoing any immediate trade rumors or free-agency flirtations that had been swirling around him since draft night. “Dallas believed in me from day one,” Flagg said in the clip, his voice steady but laced with emotion. “This city, this team, this organization—it’s home. I’m all in for the long haul.”
The announcement, timed perfectly ahead of the Mavericks’ pivotal matchup against the surging Los Angeles Lakers on Wednesday, couldn’t have come at a better moment for a franchise that’s been navigating choppy waters. Dallas sits at 12-9 on the season, a middling record that’s left GM Nico Harrison under fire from a fanbase still smarting from last year’s Western Conference Finals heartbreak. Flagg, selected No. 1 overall in the 2025 NBA Draft after a legendary one-and-done stint at Duke, has been the lone beacon of hope in a lineup plagued by injuries to stars like Kyrie Irving and inconsistent production from Luka Dončić. Averaging 16.8 points, 6.7 rebounds, and 3.4 assists through 21 games—numbers that belie his true impact on both ends of the floor—Flagg has quickly become the emotional core of a team desperate for stability.
But this isn’t just any extension talk. Sources close to the situation tell Athlon Sports that Flagg’s camp, led by his no-nonsense agent Drew Tellem, negotiated a rookie-scale max deal with incentives that could push the total value north of $250 million over five years. It’s a bold vote of confidence in Harrison’s vision, especially after the GM’s controversial decision to trade away Anthony Davis in the offseason for a package of picks and young talent centered around Flagg. “Coop’s not just a player; he’s the future,” Harrison said in a post-announcement presser at American Airlines Center. “We’ve seen what he can do as a rookie—defend like a vet, score in bunches, and lead without saying a word. This locks in our timeline. No more quick fixes; we’re building around him.”
Flagg’s journey to this point reads like a Hollywood script. Hailing from Newport, Maine—a tiny town of just 3,000 where basketball dreams often fade into the New England fog—the 6-foot-9 forward reclassified in high school to accelerate his path to Duke. There, under coach Jon Scheyer, he exploded onto the scene, averaging 19.2 points, 7.5 boards, and 4.2 dimes en route to a Final Four run and the Wooden Award as national player of the year. His draft night was pure theater: ESPN mics caught him whispering a four-word pep talk—”You’re next, brother”—to Rutgers-bound Dylan Harper, who went second to the Nets. The Mavericks, armed with the top pick via a lottery miracle, didn’t hesitate. “We traded up for a superstar,” Dončić quipped post-draft. “Now we just gotta keep up.”
Fast forward six months, and Flagg’s rookie campaign has been a rollercoaster of brilliance and bad luck. He notched a career-high 29 points in an overtime thriller against the Pelicans on November 20, a performance that included seven rebounds, five assists, and a game-sealing block on Zion Williamson. But illness struck hard last week, sidelining him for the Knicks game on November 19 and forcing Dallas to a gritty 106-102 loss to Miami without their prodigy. “It’s tough watching from the bench,” Flagg admitted in the video, showing clips of his recent workouts. “But it lit a fire. I’m back, stronger, and ready to chase rings here.”
The timing of the announcement isn’t coincidental. With the Mavericks facing a brutal stretch—Lakers, Warriors, Nuggets, and Clippers all in the next 10 days—Flagg’s words serve as a rallying cry. Teammates flooded his mentions with fire emojis and pledges of loyalty; Dončić posted a photo of the duo hoisting the Larry O’Brien Trophy in mock fashion, captioned “Soon.” Even Scheyer, Flagg’s college mentor, chimed in: “Proud doesn’t cover it. Duke prepared him, but Dallas is where he becomes a legend.”
League-wide reactions poured in faster than a fast break. LeBron James, ever the statesman, tweeted, “Smart kid. Build where you’re planted. Congrats, Coop.” On the flip side, rival execs grumbled anonymously about Dallas locking up the draft’s crown jewel. “He’s untradeable now,” one Eastern Conference GM told Athlon Sports. “Nico just won the offseason… again.” Analysts like ESPN’s Brian Windhorst praised the move as a masterstroke, noting Flagg’s advanced metrics: a +12.3 net rating, top-10 in steals per game among rookies, and a defensive versatility that evokes a young Kawhi Leonard.
Yet, beneath the euphoria lies the real story: Flagg’s announcement is as much about maturity as money. At 18, he’s already shouldered the weight of expectations that crushed lesser talents. Remember the pre-draft hype? Scouts called him “the next Kevin Durant with LeBron’s motor.” He’s delivered in spurts—a 22-point, 10-rebound double-double against the Timberwolves on November 17, where he guarded Anthony Edwards into submission—but consistency has been the bugaboo. Turnovers creep in during crunch time, and his three-point stroke (28% on low volume) needs seasoning. “I’m not perfect,” Flagg said Monday. “But I’m hungry. This extension? It’s fuel.”
For Mavericks fans, weary from a decade of “almosts,” Flagg’s vow is manna from heaven. Chants of “Fire Nico” echoed through the arena just weeks ago, but now? Optimism crackles in the air. Season-ticket renewals spiked 15% overnight, per team sources, and Flagg’s No. 32 jerseys flew off shelves at the team store. He’s even dipping into philanthropy: Last weekend, he and twin brother Ace hosted their second annual youth camp in Maine, drawing 200 kids and raising $50,000 for local scholarships. “Basketball gave me everything,” Flagg told the campers. “Time to give back.”
As the NBA calendar flips toward the holidays, all eyes turn to Dallas. Can Flagg, alongside a resurgent Dončić (28.4 PPG) and a healthy Irving, propel the Mavs into contention? Early simulations from FiveThirtyEight peg them at 48 wins and a 65% playoff probability—up from 42% pre-announcement. But numbers only tell part of the tale. This is about a kid from nowhere who chose to stay put, betting on himself and a franchise that’s betting right back.
In the video’s closing seconds, Flagg flashed that trademark grin—the one that says he’s got the weight of the world and doesn’t mind. “See y’all at the parade,” he signed off. Bold words for a rookie. But if Monday’s bombshell is any indication, Cooper Flagg isn’t just turning heads. He’s changing the game.
