Despite having a massively successful 2025-26 season, the Spurs still struggled with a simple but frustrating flaw. Worse yet, turnovers gifted the Knicks additional possessions needed to defeat the Spurs and win the championship. Young teams often struggle with turnovers, but San Antonio's young core gained plenty of experience during last season's long playoff run.
