LAS VEGAS – Morez Johnson Jr. dismantled the Lakers’ defense. The Mavericks rookie posted a game-high 28 points, 14 rebounds, and 3 blocks in Dallas’ 94-89 upset victory on Day 3 of the 2026 NBA Summer League. The loss drops Los Angeles to 1-2 in the tournament.
Johnson dominated both the paint and the perimeter. He shot 11-of-17 from the field, including two mid-range jumpers that forced Lakers defenders to respect his range. The 19-year-old forward now leads all Summer League rookies in Player Efficiency Rating.
Arthur Kaluma’s three-pointer with 4:12 remaining shifted momentum. The shot cut the Lakers’ lead to 85-84. Johnson then scored 6 unanswered points in the final 90 seconds.
The Lakers’ early 12-point lead evaporated by the third quarter. Turnovers were the primary culprit – Los Angeles committed 19, leading to 24 Mavericks points.
Bleacher Report’s Day 3 coverage highlighted Lakers prospects Avila and Flemings. Avila finished with 18 points on 7-of-12 shooting, showcasing an effective inside game. Flemings contributed 6 assists and 3 steals, but his perimeter defense was the standout – he held his primary assignment to 2-of-7 shooting.
| Player | Points | Rebounds | Assists | FG% |
|---|---|---|---|---|
| Morez Johnson Jr. (DAL) | 28 | 14 | 4 | 64.7% |
| Avila (LAL) | 18 | 7 | 2 | 58.3% |
| Flemings (LAL) | 10 | 4 | 6 | 44.4% |
| Arthur Kaluma (DAL) | 13 | 5 | 3 | 50.0% |
The upset exposes two specific Lakers weaknesses. First, interior defense against athletic bigs – Johnson’s 14 rebounds included 5 offensive boards. Second, late-game execution – the Lakers scored only 16 points in the fourth quarter.
For the Lakers’ front office, the game provides data points. Avila’s scoring efficiency (58.3% FG) strengthens his case for a two-way contract. Flemings’ playmaking (6 assists, 3 steals) suggests NBA-ready defensive instincts. But neither player solved the fundamental problem of containing a versatile offensive threat like Johnson.
The Mavericks’ win also elevates Johnson’s draft stock. Scouts now project him as a potential lottery pick in the 2027 NBA Draft, should he declare after his sophomore season.
Dallas plays the Kings on Day 4. The Lakers face the Jazz, needing a win to stay in playoff contention.
