Cooper Flagg enters his rookie season as one of the most-hyped newcomers in quite some time.
The Dallas Mavericks took the former Duke star with the No. 1 overall pick in the 2025 draft, as Flagg takes over as the franchise player with Luka Doncic now on the Los Angeles Lakers. Flagg joins Anthony Davis to form a dynamic duo early in the year, with point guard Kyrie Irving still recovering from a torn ACL.
Flagg opens his NBA career on Monday night, as the Mavericks host the Oklahoma City Thunder in the first preseason game of the year. Since the Thunder are the defending NBA champions, this game marks a more interesting matchup than a standard preseason NBA game.
Here's a look at how Flagg performed in his first preseason game in the NBA.
