The Western Conference Finals shift to San Antonio for a pivotal Game 3, with the Oklahoma City Thunder and San Antonio Spurs tied at one game apiece. San Antonio won a double-overtime classic in the opening game, while OKC responded nicely in Game 2 to even things up. Now the Spurs have their first taste of home-court advantage in this series, and will try to take advantage and get back in front in this best-of-seven matchup. Below, I break down all the action and make my Thunder vs Spurs Game 3 prediction.

Victor Wembanyama has been the story of this series so far in his first career conference finals. The Frenchman scored 41 points and grabbed 24 rebounds in San Antonio's Game 1 win in double overtime over the Thunder. He was held to just 21 points in Game 2 on 50% shooting. Those efficiency numbers are nice, but San Antonio needs more scoring volume from their top star to win this series moving forward.
Physicality without fouling on defense has been the driver of success for the Oklahoma City Thunder over the last couple of years. That is still the case here, as the Thunder allowed the Spurs to go to the free-throw line 29 times in Game 1, and reduced that number to 17 attempts in Game 2. If the Thunder can play physical defense without sending San Antonio to the line too often in Game 3, they could take their first lead in this series.

Oklahoma City enters Game 3 relatively healthy, which has allowed the Thunder to maintain consistent defensive rotations and stagger primary ball-handlers effectively throughout the series. Their bench units have sustained defensive pressure without a significant drop-off, particularly in non-star minutes.
Injuries are becoming a factor for the Spurs going into Game 3. De'Aaron Fox has been dealing with an ankle injury early in the series, while Dylan Harper suffered a leg injury in Game 2. Depth was already a question for the Spurs against a deep Thunder team, and that difference could grow if Fox or Harper continues to be hobbled.

I lean toward the Thunder as the best bet for Game 3 of the Western Conference Finals. OKC has a ton of talent, and they are also the healthier team heading down the stretch in the West. Add the edge that comes from OKC's championship experience, and we should see the Thunder take the lead here, as the injury uncertainty around Wembanyama's supporting cast could have a devastating impact on the Spurs' chances of reaching the Finals.
