Dallas Mavericks rookie Cooper Flagg, the 19-year-old No. 1 draft pick, outdueled NBA legend LeBron James in a 134-128 win over the Los Angeles Lakers. Flagg tallied 45 points, 8 rebounds and 9 assists, further cementing his case for NBA Rookie of the Year against fellow rookie Kon Knueppel of the Charlotte Hornets.

Why it matters

Flagg's performance against one of the NBA's all-time greats in LeBron James showcases the teenager's immense talent and potential. At just 19 years old, Flagg is already making a strong case to be named the league's top rookie, outpacing fellow first-year standout Kon Knueppel in several statistical categories despite having a heavier offensive load as the Mavericks' primary creator.

The details

In the win over the Lakers, Flagg made a crucial short turnaround jumper with 3:26 remaining to give the Mavericks a 10-point lead. He then went 4-for-4 from the free throw line to help Dallas hold off a late Lakers comeback. Flagg's 96 points over the last three games, including a 51-point explosion against the Orlando Magic, have further bolstered his Rookie of the Year candidacy.

What they’re saying

“I mean, he's obviously special. I've seen that all the way back to like the AAU days when he was coming up in the ranks and playing with his team out of Maine and he was doing the things that he was doing on the circuit. So, knew he was special from then, and he's just taken that from to what he was doing back home to the AAU circuit to Duke to now here and he's getting better and better and better. Looks like he loves the game. He's putting in the work, and he's gotten better.”

“I just don't understand why anyone else can be Rookie of the Year. He's done everything. Especially at his age. The things he's doing, it's unbelievable.”

“It's two different ballparks. He's 19, doing what he's doing. Being the main guy is a lot harder than being a rotational player hitting corner shots or just hitting 3s. He's initiating most of our offense. To be 19 doing that is unheard of.”
