Spurs face series crisis as Hartenstein neutralises Wembanyama in Western Conference Finals
San Antonio’s reliance on perimeter shooting and lack of interior scheming has allowed Oklahoma City to seize control of the 2026 playoffs.
The Oklahoma City Thunder have seized a commanding 3-1 lead in the 2026 NBA Western Conference Finals, capitalising on a strategic shift that has effectively neutralised San Antonio Spurs star Victor Wembanyama. Following a 123-108 victory in Game 3 on Friday, the Thunder have exposed a critical disconnect in San Antonio’s offensive approach, forcing the Spurs into a precarious position as they look to avoid elimination.
Central to Oklahoma City’s success has been the deployment of centre Isaiah Hartenstein, whose physical strength has restricted Wembanyama’s ability to operate in the paint. Hartenstein’s presence has pushed the Spurs’ primary scorer towards the perimeter, where he has attempted 12 three-pointers over the final two games compared to just two in the series opener. While Wembanyama maintains elite statistical output, averaging 29 points and 15 rebounds, his impact has been diluted by a shift away from his most advantageous scoring zones.
San Antonio head coach Mitch Johnson has faced scrutiny for insufficient offensive scheming to counter this defensive adjustment. Analysts note a lack of fundamental plays such as rim rolls, duck-ins, and rapid reversals designed to get the ball inside to Wembanyama. This tactical deficit has allowed Thunder coach Mark Daigneault to utilise Hartenstein’s size to deny deep post positioning, forcing Wembanyama into less efficient isolation scenarios or long-range attempts that Oklahoma City is willing to concede.
The disparity in team depth further compounded San Antonio’s struggles, with the Thunder’s bench outscoring the Spurs’ reserves 71-18 in Game 3, excluding garbage-time points. Statistical analysis reveals the Spurs were plus-21 with Wembanyama on the court but minus-38 when he was off, highlighting the team’s heavy reliance on his presence despite the loss. The Spurs’ inability to maximise Wembanyama’s interior advantage, combined with a significant drop-off when he rests, has left them vulnerable to Oklahoma City’s superior physicality and depth.
Wembanyama’s shot selection has fluctuated throughout the series, with 13 of his 18 shots in Game 3 coming from inside the arc, a departure from the previous games where he relied more heavily on three-pointers. However, late-game efforts to fight for deep position, including an and-one layup in the fourth quarter, came too late to alter the outcome. With the series shifting back to Oklahoma City, the Spurs must address both their offensive schematic failures and Wembanyama’s conditioning to remain competitive.
