Despite a self-proclaimed “not great” performance, Dallas Mavericks rookie Cooper Flagg showcased glimpses of his potential, recording a double-double in his highly anticipated NBA debut. While his shooting struggled, the context of facing Victor Wembanyama and the complexities of his new role offer vital lessons for the 2025 first overall pick.
The stage was set, the hype was real, and the basketball world watched as Cooper Flagg, the first overall pick in the 2025 NBA Draft, made his regular season debut for the Dallas Mavericks against the San Antonio Spurs on October 23, 2025. This matchup, notably featuring a showdown with 2023’s top pick, Victor Wembanyama, promised fireworks. While Flagg’s performance was a mixed bag, it provided invaluable early insights into his journey in the league.
A Debut of Highs, Lows, and Learning Moments
Flagg’s entry into the NBA was nearly spectacular, attempting an alley-oop just seconds into the game that ultimately clanked off the rim. This moment, as he later reflected, foreshadowed an offensively quiet first half where he went scoreless. The Duke product finished the game with a double-double, tallying 10 points and 10 rebounds in 32 minutes. However, his shooting efficiency was a concern, converting just 3-of-14 from the field in one account, and 4-of-13 in others. He also committed three turnovers, highlighting the adjustment to the NBA pace.
When asked about his performance, Flagg was candid. “Not great,” he stated, as reported by the team website. “Obviously, I didn’t play incredibly well. But you got to move past it and try to focus on Friday [against Washington].” This mature outlook, even in disappointment, resonated with fans and coaches alike.
Coach Kidd and Teammates Preach Patience
Despite the uninspiring stat line, Mavericks head coach Jason Kidd offered a supportive perspective. “I thought Cooper played within himself,” Kidd commented. “He took what the defense gave him. Was making plays and diving on the floor. He’s one that’s not going to go out there and shoot every time he touches it. He tries to play the game the right way.” Kidd acknowledged that the numbers wouldn’t reflect it, but emphasized that as a rookie, Flagg did fine and would learn from the experience, as noted by USA TODAY Sports.
Veteran teammate Anthony Davis provided crucial context, reminding everyone of the immense pressure surrounding a number one overall pick’s debut, especially on national television. “It’s game one. He’s still a rookie,” Davis said. “First-game jitters when it’s time for the real thing. He’ll be fine. It’s game one. We’re all going to be better.” Even Spurs guard Stephon Castle, last season’s Rookie of the Year and Flagg’s primary defender, observed a surprising poise. “He didn’t shoot the ball well, but he seemed a lot more poised than I thought he would be,” Castle told ESPN.com.
The Wembanyama Phenomenon and Flagg’s New Role
The game was heavily influenced by Victor Wembanyama’s explosive performance, as he erupted for a game-high 40 points and 15 rebounds. Flagg himself was in awe. “He is incredible. He is a different player,” Flagg remarked after the game. “You can’t know what it’s like until you’re out there on the court with him. It’s something I’ve never seen before.”
A significant aspect of Flagg’s debut was his unexpected role as the starting point guard, a position he had never played until joining the Mavericks. This strategic decision by Coach Kidd, aimed at accelerating Flagg’s development and adaptability, contributed to the learning curve. Dallas shot just 37.3 percent from the field and committed 16 turnovers, highlighting the collective struggles, not just Flagg’s individual performance.
Beyond the Box Score: Early Optimism for Dallas
Despite the statistical inefficiencies, Flagg’s debut offered positive signs beyond the box score. He consistently hustled on defense, actively pursued rebounds, and attempted to push the tempo in transition. These are qualities the Mavericks will look to foster, especially as they navigate the early part of the season potentially without star point guard Kyrie Irving, who is reportedly recovering from a torn ACL for the majority of the regular season.
The team’s patience with Flagg mirrors how the Spurs handled Wembanyama in his rookie season, placing him on a minutes restriction and focusing on his physical development and adaptation to the NBA game. While Flagg and Wembanyama are different players, the principle of deliberate development remains key. Flagg, who won’t turn 19 until late December, is expected to learn something new every game, making these early experiences crucial.
Looking Ahead: Adjusting on the Fly
Flagg is already looking forward to his next opportunity against the Washington Wizards. “I was excited, but I’m excited to keep going,” he said. “Obviously it hurts, the first loss being like that, but try to look forward to the next one, turn the page and get ready. We know we got a lot better [performances] than that. So stay positive and lock in on the next one. It’s basketball. It’s not always going to go your way. It’s not always going to be perfect. But you got to adjust and be better on the fly.”
His ability to secure a double-double, a feat for a first overall pick not seen since Deandre Ayton in 2018, underscores his raw talent and potential. While the initial “Welcome to the NBA Moment” may have been humbling, Flagg’s debut was a foundational learning experience for a player with immense promise. The Mavericks and their fanbase have every reason to remain excited, understanding that true greatness often begins with difficult, yet instructive, first steps.
