Cooper Flagg Dallas Mavericks 2025 NBA Summer League Game Worn Jersey | NBA 2K26 Summer League Debut

This neutral ‘White Summer League’ jersey was worn by Cooper Flagg on July 10, 2025 during the NBA 2K26 Summer League, when the Dallas Mavericks played the Los Angeles Lakers. This is the first jersey worn by Cooper Flagg in the NBA 2K26 Summer League in Las Vegas, NV. This is the first NBA jersey worn by Flagg.

Flagg finished with 10 points, 6 rebounds, 4 assists, 3 steals, and 1 block. The Mavericks beat the Lakers, 87-85. 

Flagg impacted every facet of the game. He opened his scoring with a thunderous tomahawk dunk in traffic off a fast break he started with a steal. The very next possession, he buried a baseline fadeaway over 2024 first-rounder Dalton Knecht. He added an and-1 layup in transition and later went coast-to-coast for a tough finish over former first-round pick Darius Bazley.

In what he called “one of the worst games of my life,” Flagg still made the game’s most crucial play—rotating from the weak side to block Lakers guard DJ Steward’s layup with just over a minute left in the NBA 2K26 Summer League opener. Seconds later, he led the break, collapsed the defense, and found Ryan Nembhard for the go-ahead 3-pointer that secured an 87–85 win for Dallas.

Whether it’s his timing on defense, feel as a passer, or ability to create offense in tight spaces, Flagg continues to show flashes of why he's being hailed as a franchise cornerstone—and a player who can do a bit of everything.

Flagg is coming out of Duke University, where he averaged 19.2 points, 7.5 rebounds, and 4.2 assists per game. In his lone season, he was named National Player of the Year by multiple major outlets (USBWA, NABC, AP, Wooden, Naismith) and also swept National Freshman of the Year honors. He was the ACC Player of the Year, ACC Rookie of the Year, and earned First Team All-ACC, All-Defensive Team, and All-Rookie Team selections. Flagg was a consensus First Team All-American, becoming the 22nd Duke player to earn that recognition and the 10th Duke freshman in history to be named an All-American.

He set an ACC record with 12 Rookie of the Week honors, became the first player in conference history to sweep both weekly awards five times in a season, and was named to the ACC All-Academic Team. Flagg was also named East Region Most Outstanding Player and earned NCAA All-Tournament Team honors after leading Duke to the Final Four.
