Prediction

Two of the NBA’s most complete rosters. OKC’s historic regular season record and home floor make them favorites, but San Antonio’s superior 3-point shooting and pace advantage give them a genuine path to an upset. SGA leads a Thunder team that won’t be rattled by the moment. OKC win Game 1 but the spread at -6.5 is tight given SAS’s firepower.
