Cooper Flagg is the 2026 NBA Rookie of the Year. The 19-year-old Mavericks forward swept the vote after a season that exceeded even the highest pre-draft expectations.
Flagg averaged 19.2 points, 7.8 rebounds, 4.6 assists, and 1.7 blocks. He shot 36% from three. He played in 73 games for a Dallas team that finished one game out of the play-in tournament. He was, by every reasonable measure, the best 19-year-old rookie since Luka Doncic.
The award was never in doubt. Flagg led all rookies in scoring, rebounding, and assists per game. He finished second in steals. He finished first in plus-minus among first-year players by a wide margin. The runner-up, Spurs guard Dylan Harper, had a great season too, but Flagg simply did more.
The bigger question now is what Dallas does with him. The front office made it clear at the 2026 draft that everything they do is in service of building around Flagg. They hired Dusty May, his college coach at Michigan. They drafted Morez Johnson Jr. at No. 9, another May product. They hired Mike Schmitz as general manager.
The plan is coming together. The roster is not.
Anthony Davis is still in Dallas but is constantly mentioned in trade rumors. Kyrie Irving is rehabbing from an ACL tear. PJ Washington is a quality starter but not a difference-maker. Klay Thompson is in his decline phase. The roster around Flagg looks like a team that is waiting to make a major move and has not figured out which move that is yet.
Flagg’s development next season will be the biggest story in Texas. He needs to add reliable mid-range shooting. He needs to improve his free-throw accuracy from 71%. He needs to learn to be the offensive engine on closing possessions, not just the second or third option.
The good news is that Flagg’s defensive ceiling is already All-NBA. He blocks shots from the weak side. He switches one through four. He rotates with elite timing. The Mavericks gave up the fewest points per 100 possessions with Flagg on the floor of any lineup combination they used.
Comparisons to a young Scottie Pippen feel lazy until you actually watch the film. Flagg’s combination of size, length, and skill is closer to Tracy McGrady than to any current player. The catch is that McGrady’s career was constantly derailed by injury and bad teams. Flagg’s challenge is staying healthy and making the team around him better.
Dallas can win 50 games next season if Davis stays and Irving comes back at 85%. That is the path. The other path is to use Davis as a trade chip to acquire another wing scorer or playmaker who fits next to Flagg long-term.
Either way, the Cooper Flagg era is officially underway. The Rookie of the Year hardware is the first piece of evidence that Dallas got something special at the top of the 2025 draft. The next piece is figuring out how to build a contender around him before he hits his second contract.
