Despite having a massively successful 2025-26 season, the Spurs still struggled with a simple but frustrating flaw. The Spurs struggled with turnovers at times, and that came back to bite them against the New York Knicks in the NBA Finals.
They failed to close out the Knicks in not one but all four of their losses. Worse yet, turnovers gifted the Knicks additional possessions needed to defeat the Spurs and win the championship.
Fortunately, the Spurs should be far better in that area next season. Young teams often struggle with turnovers, but San Antonio's young core gained plenty of experience during last season's long playoff run.

That experience, plus veteran Tobias Harris, could help the Spurs finally solve their turnover problem next season.
The Spurs have a turnover problem they must nip in the bud
Ironically, the Spurs ranked 12th in turnovers last season; not bad, but there were times when they were reckless with the ball. The biggest culprit was Stephon Castle, who led the NBA in turnovers in his first 20 games of the season.
In all fairness, Castle managed to rein in his turnovers, and playing alongside De'Aaron Fox helped him avoid making mistakes. Then there was Victor Wembanyama, who had his own turnover problems.
In fact, he was one of the least efficient post players in the NBA last season. That was mainly due to a staggering 18% turnover rate on post-up possessions.
Wembanyama also often turned it over when taking smaller players off-the-dribble. Both are correctable issues and something the Spurs must clean up next season.
The Spurs adding Harris to the rotation should help the team's turnover problems. He has traditionally been a low-turnover player who gets buckets without being careless with the ball.
The more experienced Spurs must be better with turnovers next season
Harris also has more than double the combined experience of Wembanyama and Castle. Having another vet on the team could help keep the young Big 3 from making bone-headed mistakes.
Having another year to learn and grow should hopefully cut down on costly mistakes for Castle and Wembanyama. After all, they ranked first and second on the team in turnovers last season.
The good news is that the Spurs could become much more dangerous offensively if they lower their turnover rate. Remember, the Spurs had a staggering 42 combined turnovers in Game 1 and Game 2 of the Western Conference Finals against the Oklahoma City Thunder. Castle accounted for 20 of them.
Fixing the turnover problem could win the Spurs a championship
Had they committed, say, only 15 in each game, they would have had 12 additional possessions. The Spurs likely wouldn't have needed double overtime to beat OKC in Game 1 or have run out of gas in Game 2 and Game 3 due to fatigue.
Instead, the series went seven games, and the Spurs were banged up entering the NBA Finals, which they eventually lost. The point being that turnovers can be even more costly than in just a single game.
Thus, San Antonio should do everything possible to cut down on those mistakes next season. By doing so, they could very well have enough to win a championship.
