Cooper Flagg made his NBA Summer League debut Thursday night and although he and the Dallas Mavericks earned the win, the No. 1 NBA Draft pick called it “one of the worst game of my life.”

LAS VEGAS (AP) — Cooper Flagg strolled into UNLV’s Thomas and Mack Center at 4:17 p.m. on Thursday, wearing Dallas Mavericks gear, bright white New Balance shoes, and an emotionless look on his face as he passed through security.

Heading into his sophomore campaign, the son of the Lakers' future Hall of Fame inductee and 21-time All-Star LeBron James will be aiming to eventually break into the team's rotation after tearing up the G-League for the franchise's South Bay affiliate in 2024-25.
