Flagg excited the crowd at the 4:30 mark of the first quarter, jamming home the first points in the Summer League. He finished the first quarter with six points, one rebound and a steal.

Early in the second quarter, Flagg nearly sent every fan in the building into a frenzy when he made a spin move into the paint and attempted a one-handed slam dunk over 7-foot Christian Koloko. The ball caromed off the back of the rim and still drew plenty of oohs and ahhs.

Flagg finished the first half with eight points on 4-of-11 shooting, including 0 for 3 from 3-point range. He also had three rebounds, two steals and one assist.

Generally filled with Lakers fans when the team plays in the summer, the arena was full of emotion with a fair share of Mavericks fans in attendance to see the 2025 National college player of the year.

Like 15-year-old Baer Epple, 15, who was seated with his father Chad in the third row from the court, donning Dirk Nowitzki’s Mavericks jersey.

Epple said he’s been following Flagg since before his Duke days, beginning with his junior year at Nokomis Regional High School in Newport, Maine.

The 15-year-old who is in Las Vegas from Seattle for an AAU tournament said he’s been a Mavericks fan for roughly four years.

“Even more of a fan now that they got Cooper Flagg,” Epple said. “Hopefully he does good, that’d be pretty cool to see. I don’t want him to be like a bust or anything.”

Mavericks coach Jason Kidd told The Associated Press before the game he’s looking for nothing more than effort and grit in his team’s opening game, as he wants them all playing hard.

“This summer league is a little different when you have this type of turnout,” Kidd said. “But the guys have had a couple practices. There’s going to be some turnovers. I just want to see how they respond to a couple of mistakes being made, no one’s gonna play a perfect game and be unselfish.”

As for his prize draft pick: “We’re all excited,” Kidd said of Flagg. “Seen enough of him on tape, so now it’s good to see him on the floor.”
