Following the conclusion of the 2026 Las Vegas Summer League, NBA rookies have begun to reshape expectations for the upcoming season. While high-scoring debuts and defensive standouts have captured attention, scouts are re-evaluating long-term projections based on performance across multiple games in the tournament. As noted by evaluators, while one week in Las Vegas should not completely rewrite draft evaluations, it provides valuable new information for scouts who entered the summer with varying levels of certainty regarding specific players.

Grizzlies and Mavericks Advance to Semifinals
Tournament play has separated the most prepared rookie classes from those still adjusting to the professional game. Cameron Boozer and the Grizzlies defeated the Hawks to earn a spot in the 2026 NBA Summer League semifinals. The tournament featured the Lakers, Rockets, Grizzlies, and Warriors advancing to the semifinals, where they competed for the championship. Led by No. 25 pick Sergio De Larrea (9 rebounds, 14 assists) and the high-flying acrobatics of Kaodirichi Akobundu-Ehiogu (12 points, 5 rebounds), the Mavericks defeated the Thunder 97-87 to open Thursday’s action. The Rockets beat the Nets 103-83, led by backcourt mates Bruce Thornton (23 points) and Tristen Newton (20 points), giving them a 3-1 record and a spot in the semifinals. The Lakers advanced to the semifinals by earning a 105-82 win over the Bulls, as six double-figure scorers overcame Caleb Wilson’s 21 points and 8 rebounds. The Warriors vaulted into contention for a semifinals spot by beating the Knicks 87-77, later clinching their berth after the Blazers won the final game of the night.

Nate Ament and Kingston Flemings Adjust to Professional Play
Scouting Adjustments: Risers and Raw Prospects

Scouts are using the small sample size of Summer League to refine their views on players who entered the draft with different expectations. While some prospects looked comfortable in NBA-level roles, others struggled with the physicality of the game. Milwaukee’s Nate Ament, the 13th overall pick—a selection the Bucks snagged in the Giannis blockbuster—has been an offensive afterthought. Ament is, at least in theory, a 6’10” forward who can dribble, pass, and shoot. However, he has been a brutal combination of too passive and not nearly physical enough, recording 21 total points, three assists, and seven turnovers through three outings. This is not shocking, as Ament was always viewed as raw in terms of his skills and his frame. If the hope was that he would help ease the sting of losing Antetokounmpo, that relief does not appear to be coming any time soon.

Conversely, other players have seen their stock rise through defensive intensity. Kingston Flemings, the No. 8 pick, was one of the best playmakers and defenders observed during the week. Through four games, he averaged 6.8 assists, 1.5 steals, and 1.2 blocks per game. His shooting has not hit, but between his ball security, leadership, and defense, he is settling in quickly. Fellow first-rounder Zuby Ejiofor was also strong defensively, averaging 3 stocks along with 8 points, 9 rebounds, and 2.5 assists. Second-year forward Asa Nowell is making steady progress, despite shooting 43.8% across Salt Lake City and Las Vegas. Additionally, Hugo González looks ready for a real bump in minutes this season following Jaylen Brown’s departure.

The 2026 rookie class has been active, though not every top prospect has been available. Except for No. 20 pick Jayden Quaintance and No. 21 pick Karim Lopez, who are injured, every first-round selection appeared in multiple games at the Las Vegas summer league. The league has also remained busy with broader organizational updates. The NBA is currently investigating a deal between the Bucks and Trent, and the league has confirmed it will not punish Bam for an altercation with Herro. Meanwhile, the Miami Heat are managing internal expectations, with Giannis stating he will do whatever it takes
to win with the Heat, and Pat Riley making a pitch to LeBron James, who has not yet revealed his next team.
As teams transition from Summer League to the regular season, the focus shifts to how these rookies integrate into established rotations. With the tournament wrapping up, executives are left to weigh the small-sample variance of Vegas against the long-term potential that originally drove their draft decisions.
