The 2025 NBA Summer League in Las Vegas commenced with an electrifying matchup between the Dallas Mavericks and the Los Angeles Lakers on Thursday, July 10, 2025, at the Thomas & Mack Center. This highly anticipated game marked the professional debut of No. 1 overall pick Cooper Flagg for the Mavericks, who faced off against Bronny James of the Lakers, son of NBA icon LeBron James. The contest, broadcast nationally on ESPN, garnered immense attention, with ticket prices soaring to near-record highs for a Summer League game, reflecting the widespread intrigue surrounding these burgeoning talents (USA Today, Yahoo Sports).
The Dallas Mavericks ultimately secured a narrow 87-85 victory over the Los Angeles Lakers in a back-and-forth affair. The Mavericks started strong, leading 19-17 after the first quarter, but the Lakers surged ahead to take a 47-43 lead into halftime. Dallas regained control in the third period, entering the final quarter with a 68-62 advantage. The game’s climax arrived in the final minute, with Ryan Nembhard sinking a crucial 26-foot three-pointer, assisted by Cooper Flagg, to put the Mavericks up 87-85 with just over a minute remaining, a lead they held until the final buzzer (ESPN).
Cooper Flagg’s much-anticipated debut saw him finish with 10 points, 6 rebounds, 4 assists, 3 steals, and 1 block in 31 minutes of play (ESPN). While his shooting efficiency was a modest 5-for-20 from the field and 0-for-5 from beyond the arc, he showcased his versatility and impact across the court. Mavericks coach Jason Kidd had previously indicated plans to utilize Flagg at point guard, and the rookie demonstrated his ball-handling and playmaking abilities throughout the game (Yahoo Sports). Flagg’s first professional basket came emphatically via a steal and a transition dunk, which seemed to settle him into the game (USA Today).
Bronny James, playing 20 minutes for the Lakers, contributed 8 points on 2-for-7 shooting (1-for-5 from three-point range) along with 2 rebounds and 1 turnover (ESPN). Notably, James, known for his defensive prowess, was tasked with guarding Flagg at times during the second quarter. Despite giving up seven inches in height, James aggressively disrupted Flagg’s attempts, though Flagg did manage to score over him on one occasion (USA Today). James had previously played in the California Classic Summer League, scoring 10 points in a win against the Miami Heat on July 6 (USA Today).
The Mavericks were led in scoring by Ryan Nembhard, who delivered a strong performance with 21 points and 5 assists (ESPN). Miles Kelly also chipped in with 17 points for Dallas. For the Lakers, Cole Swider was the standout scorer, pouring in 22 points on efficient 6-for-10 shooting, including 6-for-9 from three-point range, and grabbing 10 rebounds (ESPN). Swider’s strong Summer League play earned him a spot on the 2025 All-California Classic Team (Yahoo Sports). Dalton Knecht added 15 points for the Lakers, showing improved form after a challenging California Classic (ESPN, Yahoo Sports).
Dallas shot 43.6% from the field compared to Los Angeles’s 37.7%. The Lakers, however, had a better three-point percentage at 40.5% to the Mavericks’ 32.1%. The Lakers also outrebounded the Mavericks 45-38, while Dallas committed fewer turnovers (9) than Los Angeles (11) (ESPN). The game was officiated by Che Flores, Robert Hussey, and Austin Spiker (ESPN). The underlying narrative of a burgeoning rivalry between the Mavericks and Lakers, fueled by the blockbuster Luka Doncic-Anthony Davis trade last season, added another layer of intrigue to this Summer League opener (USA Today). Mavericks star Kyrie Irving was also in attendance, watching his team’s Summer League debut (USA Today).
The highly anticipated clash lived up to its billing, offering fans a glimpse into the future of the NBA and setting an exciting tone for the rest of the Summer League. Both Flagg and James, along with their teammates, provided moments of brilliance and areas for growth, promising an engaging tournament ahead.
