Cooper Flagg’s Meteoric Rise: Mavericks Rookie Makes History in First Month
It’s not often an 18-year-old rookie steps into the NBA and immediately looks like he belongs - not just as a contributor, but as a difference-maker. Yet that’s exactly what Cooper Flagg has done for the Dallas Mavericks. On Monday, the league made it official: Flagg was named the NBA’s Western Conference Rookie of the Month for October and November - and frankly, it’s hard to imagine anyone else getting the nod.
This isn’t just a promising start. This is a historic one.
Flagg’s Numbers Tell the Story - and Then Some
Through his first 20 NBA games, Flagg has averaged 16.7 points, 6.6 rebounds, 3.5 assists, and 1.4 steals while logging nearly 34 minutes per night. He’s shooting an efficient 46.2% from the field and already proving to be one of the league’s most clutch performers - his 48 clutch points rank fourth in the NBA, and he leads all players in clutch field goal percentage at 56% (minimum 20 attempts).
Let’s pause there. We’re talking about an 18-year-old rookie, fresh out of Duke, not just holding his own in the league’s pressure moments - but excelling.
That kind of poise isn’t taught. It’s innate.
And the accolades don’t stop at the monthly award. Flagg has already etched his name into the NBA record books multiple times in just over a month of action.
Making History - One Game at a Time
On November 29 against the Clippers, Flagg dropped 35 points - becoming the youngest player in league history to hit that mark in a single game. What made the performance even more remarkable?
He did it without making a single three-pointer, joining Zion Williamson and Blake Griffin as the only players in the past 30 years to score 35 within their first 20 games without hitting from deep. That’s a rare blend of efficiency, physicality, and control.
The night before, against the Lakers, Flagg dished out 11 assists - the most ever by a player his age. He added 13 points, seven boards, and three steals, joining LeBron James and Josh Giddey as the only teenagers to post a 13-7-11-3 stat line.
And on November 21 versus New Orleans, he notched his fifth 20-point game, passing Kobe Bryant for second-most 20-point outings by an 18-year-old. That night, he became just the second player at that age - alongside LeBron - to post at least 25 points, five rebounds, and five assists in a game.
These aren’t just stats. These are milestone moments. And Flagg is stacking them up like a seasoned vet.
A Rookie Leading the Pack
Flagg’s production isn’t just historically impressive - it’s also putting him at the top of this year’s rookie class. He ranks second among rookies in total points (358), first in rebounds (139), tied for first in assists (71), second in steals (29), and fourth in blocks (13). He’s the only rookie to rank in the top five in all five of those categories.
He’s also tied for the most double-digit scoring games (20) and double-doubles (3) among rookies. That kind of across-the-board impact is rare - especially for a player still months away from his 19th birthday.
Veteran Praise and a Team Leaning In
From the jump, Dallas has leaned heavily on Flagg - and he’s responded with maturity and confidence well beyond his years. Injuries have forced him into expanded roles, but instead of shrinking under the spotlight, he’s embraced it. Whether he’s playing off the ball, initiating offense, or defending multiple positions, Flagg has shown he’s not just ready - he’s thriving.
Veteran center Anthony Davis has been one of his most vocal supporters, particularly impressed by Flagg’s ability to get downhill and attack.
“He’s going to continue to be aggressive,” Davis said. “Him getting downhill, getting to his mid-range and getting to the basket, he’s unstoppable. We told him to play to his strengths… He still has a long ways to go, and that’s scary.”
That’s a telling quote - not just because of the praise, but because of the word “scary.” When a player is this good this early, and still has significant room to grow, it’s hard not to think about what the ceiling might be.
Mavericks head coach Jason Kidd echoed those sentiments, highlighting Flagg’s feel for the game and his ability to deliver in crunch time.
“In the open court, he’s one of the best in this league only at 18,” Kidd said. “He lets the game come to him, and I thought he delivered, especially down the stretch for us.”
Flagg Staying Grounded, Focused on the Team
For all the hype and headlines, Flagg remains grounded. He’s quick to credit the veterans around him for helping him adjust to the NBA and stay locked in.
“It starts with my teammates,” Flagg said. “They’re just giving me a lot of confidence and helping me get in that mindset… Just having that confidence and going out there and being in attack mode from the jump.”
He also shared the mindset that’s carried him through the transition from college to the pros.
“Don’t second-guess yourself. Ever.
I’m here for a reason. Be who I am.”
That’s the kind of mentality you want in a franchise cornerstone - confident, but coachable. Hungry, but humble.
Laying the Foundation for the Future
Flagg’s early-season surge has been more than just a flash of rookie brilliance. It’s been a steady, evolving showcase of what happens when talent, work ethic, and opportunity align. He’s already taken on stretches as the team’s primary ball-handler, and Kidd continues to trust him with big minutes in big moments.
Beyond the box score, it’s his intangibles - the poise, the IQ, the calm in chaos - that have stood out. As Kidd put it, “He understands how to play the game the right way.”
With two rookies already playing major roles in Dallas, Flagg’s rapid rise isn’t just a feel-good story - it’s the foundation of something bigger. Something that could shape the Mavericks’ future for years to come.
And if the first month is any indication, we’re just getting started.
