Spurs Crush Mavericks 125-92 in Season Opener, Wembanyama Leads the Way

On October 22, 2025, the San Antonio Spurs routed the Dallas Mavericks 125‑92 in the NBA’s 2025‑26 season opener at the American Airlines Center in Dallas, Texas. The game vaulted Victor Wembanyama, a 21‑year‑old French forward, to a 31‑point, 10‑rebound, 3‑block highlight reel that left fans and analysts re‑thinking the league’s power balance.

Veteran head coach Jason Kidd, in his third season behind the Mavericks’ bench, had publicly declared before tip‑off that rookie center Dereck Lively II was “ready to go right now” after a hamstring scare in the Las Vegas Summer League. That optimism vanished quickly when longtime big man Daniel Gafford was ruled out with a left‑ankle sprain sustained on October 18, forcing Lively II into the starting lineup.

Meanwhile, the Mavericks’ newest guard, 19‑year‑old Cooper Flag, made a splash with a steal on the opening possession and finished with 17 points before fouling out. Across the divide, Spurs rookie center Stephon Castle logged 18 points, six rebounds and six assists under the guidance of first‑year head coach Mitch Johnson, who praised his protégé’s poise in post‑game remarks.

Background and Preseason Hype

Going into the night, the most debated storyline was the Mavericks’ “crucial question mark at center.” Gafford’s $40.5 million, three‑year deal signed in July signaled Dallas’ intent to dominate the paint, yet a lingering ankle sprain threatened to leave the team shorthanded. Lively II, a 7‑foot‑1, 21‑year‑old who missed the September Summer League due to a hamstring issue, was thrust into the spotlight. Analysts wondered whether the rookie could withstand the Spurs’ veteran frontcourt and, more importantly, the league‑wide surge of versatile big men.

On the Spurs side, anticipation centered on Wembanyama’s second year. After a rookie campaign that earned him the 2023‑24 Rookie of the Year award, the San Antonio faithful expected a leap in scoring efficiency and defensive impact. Head coach Johnson, hired in the summer after a stint as an assistant with the Toronto Raptors, promised a “more aggressive, fast‑paced offense” that would give his young stars space to operate.

Game Summary and Key Moments

The first quarter set the tone early. At 00:32, a missed goaltending call on Wembanyama’s dunk attempt sparked a brief dispute, but the referees let the play stand, and the French phenom responded with a thunderous tomahawk dunk at 01:22. By the end of the quarter, the Spurs led 38‑21, buoyed by Castle’s three‑point barrage and Wesley’s (mis‑identified on the broadcast as “Vel”) clutch three‑pointer.

The Mavericks tried to claw back. Flag’s steal on the opening tip‑off led to a fast‑break layup, and Jordan Washington, a two‑way contract guard signed on September 28, added a driving layup with contact at 06:05. Yet each surge was quickly stifled by Wembanyama’s defensive versatility – a block at 05:44 that the commentator likened to “playing against your dad in the driveway when you’re eight.”

Mid‑game, the Spurs widened the gap. At 06:56, Flag hit back‑to‑back buckets in the third quarter, only to foul out with four minutes left, turning the momentum back to San Antonio. A 12‑point swing with 3:18 remaining in the third gave the Spurs an 89‑67 lead that proved unassailable.

The final buzzer sounded at roughly 9:45 PM UTC after a 2‑hour‑15‑minute contest. The box score read 125‑92, with Wembanyama shooting 12‑of‑20 (four from deep) and Castle converting 7‑of‑14 while dishing out three assists.

Rookie Debuts and Individual Performances

Cooper Flag’s debut was a mixed bag. His 17 points, two steals, and three assists showcased offensive upside, but four personal fouls and a late foul‑out highlighted the learning curve of NBA minutes. “I just wanted to stay out of trouble and do what I practiced,” Flag told reporters, a sentiment echoed by many first‑year players adjusting to the league’s physicality.

Stephon Castle, the Spurs’ fourth‑overall pick, proved he could be a multi‑dimensional contributor. His 18 points came on a mix of post moves and perimeter shooting, while his six rebounds and six assists reflected a growing court vision. “I feel comfortable feeding the ball to Victor and creating space for our wing players,” Castle said.

Wembanyama’s 31‑point night was the headline, but the supporting cast mattered. Blake Wesley (mis‑heard as “Vel”) added 12 points, and the bench unit – featuring second‑round pick Yor Anei (identified as “Champagnie”) – poured in 37 points, underscoring the Spurs’ depth.

Impact on Mavericks’ Center Situation

Gafford’s absence turned into a tangible malaise. Without his 6‑foot‑10, 235‑lb presence, Dallas struggled to protect the rim and secure offensive rebounds. Lively II displayed flashes of potential – 9 points, 4 rebounds, and a respectable defensive presence – yet the conditioning concerns lingered. General manager Nico Harrison confirmed that MRI results from October 20 project a 10‑14‑day recovery window, meaning the Mavericks will likely miss the first two to three regular‑season games.

The loss also forced Dallas to restructure its interior defense, relying more on perimeter pressure from Washington and Flag. While the strategy yielded a few fast‑break opportunities, it couldn’t compensate for the loss of a dedicated rim protector.

Looking Ahead for Both Franchises

For the Spurs, the decisive opening victory sets a confident tone. Johnson’s quote – “Victor’s forever opener sets the tone for what this franchise represents moving forward” – hints at an aggressive identity that could challenge Western Conference powerhouses. With a healthy roster and a deep bench, San Antonio appears poised to contend for a playoff spot earlier than many predicted.

The Mavericks, meanwhile, must navigate the early season without Gafford while integrating Lively II into the rotation. If Lively II can stay healthy and develop his footwork, Dallas may still field a competitive frontcourt. However, the early loss emphasizes the need for quicker adjustments on both ends of the floor.

• Victor Wembanyama finished with 31 points, 10 rebounds, and 3 blocks (12‑of‑20 shooting).
