‘Just Chilling By Myself’: Cooper Flagg Opens Up On Isolation Of NBA Life As A 19-Year-Old

DHJ Quick Take

  • The Reality of 19: In a candid April 1 appearance on the Pat McAfee Show, Cooper Flagg pulled back the curtain on the isolation of being the NBA’s youngest player, trading the Duke dorms for a quiet life of “chilling by myself” in Dallas.
  • Adulting in the League: Beyond the 82-game grind, Flagg opened up about the steep learning curve of living alone, paying rent, and navigating a locker room of veterans with wives and children.
  • Historic Isolation: Despite the “mentally taxing” nature of a 24-52 season, Flagg remains in elite company, joining LeBron James and Luka Dončić as the only teenagers to average 20+ points per game.

DALLAS —For many 19-year-olds, there is no shortage of opportunities to spend time with friends in college. For Cooper Flagg, the business of basketball offers a different experience from what he had a year ago at Duke.

The Dallas Mavericks rookie pulled back the curtain on the personal adjustments of NBA life during a Wednesday appearance on “The Pat McAfee Show.”

“It’s a big lifestyle change,” Flagg said. “I’m in a new city living on my own, worrying about paying rent, paying for different things. Figuring that stuff out. Everybody has their own family. A lot of the guys have children and wives so nobody’s hanging out. I’m going to practice, going to the games and going home and kind of just chilling by myself.”

From the Duke Dorms to the ‘Real’ World

Last year, Flagg was playing at Duke and shared a dorm room with former teammate Kon Knueppel. As the youngest player in the NBA now, Flagg is figuring it out in a new city. Most of his Mavericks teammates are seasoned professionals with established routines and families.

The grind of the NBA schedule has added another adjustment for Flagg. He emphasized that nothing can prepare you for an 82-game season until you experience it firsthand.

“The length of the season — 82 games is a lot, and you can’t really prepare for it,” Flagg admitted. “So it’s just been things that I’ve had to learn through the year. Mentally, physically, preparing my body. Preparing my mind just to be ready for 82.”

Historic Numbers for Cooper Flagg Amid the Adjustment

At Duke, Flagg played 37 games. This season, he has already logged 64 for a Dallas team that sits at 24-52 and has been eliminated from playoff contention for the second consecutive year.

The toll of the losing has been as heavy as the schedule.

“Obviously, it’s been tough,” Flagg said. “There’s been times through the season where it’s been mentally taxing on me, not having success that I would’ve hoped for.”

Despite the frustration at home, the production on the court remains historic. Averaging 20.3 points, 6.6 rebounds, and 4.5 assists, Flagg is one of only five teenagers in NBA history to average 20+ PPG, joining Carmelo Anthony, Luka Dončić, Kevin Durant, and LeBron James. He also leads all 2025-26 rookies in total assists (290).

None of the accolades, however, has made the nights at home feel any shorter.

“It’s definitely not the start I would’ve looked for,” Flagg said, “but hopefully I’ll be able to look back on it and know that I was able to learn a lot from it.”

Flagg has six games left in his rookie season. Given the history he’s made this season, imagine what he’ll achieve after getting a full offseason to reset and work on his game, already knowing what the NBA is like?
