Dirk Nowitzki has developed a relationship with Cooper Flagg and says he remains available to the Dallas Mavericks’ young star whenever he needs advice.
Nowitzki, who spent his entire 21-year NBA career with Dallas, said he has stayed in contact with Flagg and occasionally reaches out after watching him play.
“We met a few times, and we’re obviously in contact. I write him a few things when I see something. So, he knows that I’m in his corner whenever I want him to succeed and do well. But like I said, he’s so far ahead of the curve already at that age. But if there’s ever anything that he needs, I’m more than happy to help.”
Flagg arrived in Dallas as the No. 1 overall pick in the 2025 NBA Draft and immediately became the centerpiece of the franchise following Anthony Davis’ departure at the 2026 trade deadline.
The 19-year-old forward started all 70 games he played during his rookie season, averaging 21.0 points, 6.7 rebounds and 4.5 assists in 33.5 minutes per game. He also recorded 1.2 steals and 0.9 blocks per game while shooting 46.8% from the field and 82.7% from the free-throw line.
Flagg was named Rookie of the Year after becoming the clear focal point of a Mavericks team that finished 26-56 and missed the playoffs.
His rookie campaign also placed him alongside an important figure in Dallas history. Nowitzki spent 21 seasons with the Mavericks, winning the 2011 NBA championship and earning 14 All-Star selections and 12 All-NBA honors during his career.
Nowitzki retired in 2019 as Dallas’ all-time leader in points, rebounds, games played and several other major statistical categories. His willingness to remain connected with Flagg gives the young forward access to one of the most significant figures in franchise history.
The Mavericks have embraced a youth-oriented direction around Flagg under new head coach Dusty May and president of basketball operations Masai Ujiri. Dallas added Zaccharie Risacher and Morez Johnson Jr. in the 2026 draft, while also acquiring Santi Aldama and Tarik Biberovic.
Flagg is expected to remain the foundation of that rebuilding effort heading into his second NBA season. Dallas also retains young players such as Dereck Lively II, Daniel Gafford, Max Christie and PJ Washington.
