There’s a chance Flagg could start at point guard, just as he did in the final two games of the preseason. Mavericks coach Jason Kidd admitted that he knew who his starting lineup would be for Wednesday, but held his cards close to his chest and wouldn’t reveal the first unit.

By the end of the night Wednesday, the Spurs will have more game tape of Flagg to pore over. They can only hope it isn't a horror film. This article originally published at Primetime matchup: Spurs, Victor Wembanyama open season vs. Mavericks, phenom Cooper Flagg.

San Antonio Spurs star Victor Wembanyama praised Dallas Mavericks rookie Cooper Flagg ahead of the two teams' season opener Wednesday night

Dallas Mavericks rookie Cooper Flagg will make his much-anticipated NBA regular season debut on Wednesday night.

Our experts predict where the Mavs finish in a stacked Western Conferece, if Cooper Flagg is the Rookie of the Year and more.

Moreover, taking a step further, Perkins even proclaimed that while Flagg was ranked outside of the Top 50 players in the 2025-26 season, when this campaign is done, this Duke sensation will be unanimously ranked among the Top 25 players, courtesy of his quality two-way impact.

As Flagg prepares for his first season in the NBA, the Mavericks recently decided to experiment with his versatility by placing him at point guard in the final two preseason games against the Utah Jazz and Los Angeles Lakers. He averaged 12.0 points, 4.5 rebounds and 2.0 assists across those two starts.
