A Record-Breaking Underdog Role

LeBron James, in his 23rd season and over 1,900 career games, faces an unprecedented challenge: his Los Angeles Lakers enter Game 1 of the Western Conference semifinals as 15.5-point underdogs against the top-seeded Oklahoma City Thunder. This is the largest point spread James has ever faced in any regular-season or playoff game. The Lakers, the No. 4 seed, finished off the Houston Rockets with a 98-78 win in Game 6 on Friday, taking the first-round series 4-2. They did so without Luka Dončić for the entire series and without Austin Reaves for part of it. Kevin Durant missed five of six games for the Rockets due to injuries, but the Lakers' victory set up a daunting matchup.

Thunder's Dominance in the Regular Season

The Thunder were 4-0 against the Lakers this season, and the margins were staggering. Oklahoma City won by an average of 29.3 points per game, the largest regular-season point differential between two teams from the same conference in the 2025-26 season. Three of those wins came by at least 29 points. However, there are caveats. LeBron James, Luka Dončić, and Austin Reaves played together only once, posting a minus-16 in 17.9 minutes. Dončić and Reaves sustained injuries in the April 2 contest, and all three were absent for the final meeting days later. Dončić remains out with a strained left hamstring, while Reaves returned from a strained oblique in Game 5 against the Rockets.

Dončić's Absence and the Lakers' Offensive Puzzle

If Dončić returns during the series, the Lakers face a troubling stat: they were outscored by 56 points in the 59 minutes Dončić played against the Thunder this season. The Lakers must solve both offensive and defensive puzzles to compete against the defending champions. Without Dončić, the Lakers leaned heavily on James and Reaves. James carried the team through the first round, but the Thunder present a far sterner test. Oklahoma City swept the Phoenix Suns 4-0 in the first round and have been waiting for Los Angeles.

Historic Odds and James' Playoff Underdog Legacy

The Lakers are +950 underdogs for the series, the biggest playoff underdog the franchise has been since at least 1988, according to the Sports Odds History database. For James, this is the second-largest underdog role in a playoff series of his career. The largest was in 2006, his first postseason, when the Cleveland Cavaliers were 12-1 underdogs against the Detroit Pistons in the second round; the Pistons won in seven games. The previous biggest point spread James faced was in Game 1 of the 2018 NBA Finals, when his Cavaliers were 12.5-point underdogs and lost 124-114 in overtime to the Golden State Warriors. Now, the Lakers face even longer odds.

Series Schedule and What Lies Ahead

Game 1 tips off Tuesday, May 5 at 8:30 p.m. ET on NBC/Peacock. Game 2 is Thursday, May 7 at 9:30 p.m. ET on Prime Video. The series shifts to Los Angeles for Game 3 on Saturday, May 9 at 8:30 p.m. ET on ABC, and Game 4 on Monday, May 11 at 10:30 p.m. ET on Prime Video. The Thunder's depth and defensive prowess will test the Lakers' resilience. Without Dončić, the Lakers' offense must find rhythm against a team that has dominated them. The question is whether Los Angeles can pull off a historic upset or if the Thunder will continue their march toward a repeat.
