League showdown between Bronny James and the Los Angeles Lakers and Dallas Mavericks No. 1 pick Cooper Flagg lived up to the hype.

Frenzy became bedlam on the next play. Flagg talked trash to James, ran to his spot on the left wing, pivoted off the catch and nailed the shot before turning to exult with his future Mavericks varsity teammates, who cheered him on decked out in casual wear from their courtside seats.

There hasn't been an American player with so much hype in more than a decade, at least since Flagg's new teammate Anthony Davis.

Dallas Mavericks rookie Cooper Flagg described his NBA Summer League debut as "one of the worst games of my life," but drew praise from coaches and opposing guard Bronny James after a win over the Los Angeles Lakers.

"I had a great seat," Kidd said of a highlight dunk from Flagg. "I got excited to see No. 32 get an easy one and it was with a dunk. Again, he's shown that he can handle the press. I thought the Lakers sent a double-team on the first play of the game. I think that's out of respect."
