The San Antonio Spurs walked into their playoff series against the Portland Trail Blazers with a clear defensive identity built around Victor Wembanyama. With the reigning Defensive Player of the Year anchoring the paint, San Antonio’s scheme was simple: protect the rim, force tough perimeter shots, and control tempo through length and disruption.
Game 1 validated that approach. The Spurs were able to clamp down on Portland’s offense, with Wembanyama serving as the ultimate deterrent against drives and interior scoring. But that stability quickly disappeared after Wembanyama suffered a concussion in Game 2, shifting the entire complexion of the series.
Portland attacks a suddenly vulnerable interior
Without Wembanyama patrolling the paint, Portland’s guards and wings found far more room to operate. Deni Avdija, one of the league’s most effective slashers, suddenly had clearer lanes to the rim. The absence of an elite shot blocker changed the geometry of San Antonio’s defense, forcing the Spurs into rotations they were no longer fully equipped to finish.
Scoot Henderson has also taken advantage of the situation. Through the first two games, he has elevated his scoring output significantly, averaging 24.5 points while shooting over 50% from three-point range. His ability to stretch the floor while attacking downhill has compounded San Antonio’s defensive issues.
Together, Avdija and Henderson have put consistent pressure on a Spurs defense that no longer has its primary anchor.
Luke Kornet steps into a larger role
In Wembanyama’s absence, Luke Kornet has become the Spurs’ most important interior presence. His size and rim protection have helped stabilize stretches of play, and San Antonio has looked noticeably more organized defensively when he is on the floor.
However, the drop-off becomes clear when Kornet sits. The Spurs have experimented with small-ball lineups, but those units have struggled badly with rebounding and rim protection. Portland has been quick to exploit those minutes, attacking the paint and generating second-chance opportunities.
The margin for error in Kornet’s minutes is thin, but the real danger lies in what happens outside of them.
Stephon Castle and the perimeter adjustment
Rookie guard Stephon Castle has taken on added responsibility, particularly in navigating screens and limiting penetration. His physical defense has helped slow down some of Portland’s off-ball movement, especially when trying to contain Avdija’s drives.
Still, San Antonio’s defensive structure is clearly less imposing without Wembanyama. The Spurs are being forced to rely more heavily on positioning, switching, and team rotations rather than relying on elite rim protection to erase mistakes.
Offensive response becomes essential
If San Antonio is going to survive this stretch without its star center, the offense will need to carry more weight. De’Aaron Fox, Castle, and Dylan Harper are expected to shoulder increased scoring responsibilities, especially as Portland continues to push the pace.
The Spurs also have an opportunity to leverage their versatility. Lineups featuring Julian Champagnie, Harrison Barnes, and Carter Bryant provide size and spacing even in smaller configurations, allowing San Antonio to play faster while maintaining switchability on defense.
That combination could help the Spurs punish Portland’s own weaknesses, particularly from three-point range, where the Blazers have struggled throughout the season.
The turning point: non-Kornet minutes
Ultimately, the series may come down to how San Antonio performs in the minutes without Kornet on the floor. Those stretches have been the most problematic, with the Spurs losing control of the glass and allowing Portland to attack the rim at will.
If San Antonio can survive those periods—through pace, spacing, and disciplined rotations—they can stay competitive even without Wembanyama. If not, Portland’s offense has already shown enough firepower to tilt the series.
Outlook
The Spurs are no longer just adjusting game plans—they are adjusting their identity. With Wembanyama sidelined, San Antonio’s defensive foundation has been shaken, and the series has shifted into a test of depth, adaptability, and discipline.
Luke Kornet’s presence keeps them afloat, but the Spurs’ chances of advancing may ultimately depend on whether their supporting cast can collectively compensate for the absence of one of the league’s most dominant defensive forces.
