OKC vs San Antonio: Who Wins the 2026 Western Conference Finals?
OKC vs San Antonio:
Who Wins the 2026 Western Conference Finals?
We ran the Audit Season Team Efficiency Score on both teams' most recent playoff performances. The results were historic — and almost impossible to separate. Here's what the numbers say.
The Audit Season Team Efficiency Score
Every game breakdown on this site is powered by the same proprietary model: the Audit Season Team Efficiency Score. It's a two-way rating that combines offensive and defensive performance into a single number from 0 to 100, with a letter grade attached.
The model evaluates how well a team played on both ends of the floor and adds a bonus layer for elite counting-stat performances in a single game. It's calibrated to real NBA team rating ranges — so a perfect 100 is genuinely rare.
The methodology is proprietary, but here's what the output tells you: the higher the score, the more dominant the team was across every dimension of the game — offense, defense, and volume. A grade of A or above means the team was playing at or near peak efficiency for the season.
Running the Score
We ran the model on each team's most recent playoff game — their series clinchers. This captures both teams at full momentum, heading into the Conference Finals.
Oklahoma City Thunder — Game 3 vs Los Angeles Lakers (W 131–108)
The Thunder closed out the Lakers in dominant fashion. Here's how they scored:
All three bonus categories hit for OKC. The Thunder didn't just beat the Lakers — they outclassed them on every dimension the model tracks.
Note on San Antonio's Game 6 vs Minnesota (W 139–109): Their defensive performance was historic. A Defensive Rating of 98.0 in a playoff game is something Oklahoma City hasn't seen from any opponent this postseason. San Antonio's efficiency rating actually exceeded the model's normalization ceiling — meaning the formula had to cap their score. It was that kind of performance.
Breaking the Tie
When the model scores two teams identically, we look at the factors it can't capture on its own. Here's how the tiebreaker reads heading into Game 1 tonight.
OKC wins the tiebreaker convincingly. They're better rested, hold home court for the first two games, and enter as heavy favorites. Sweeping the Lakers in the second round wasn't just efficient — it was a statement that this team had another gear available.
San Antonio's edge is narrower but real. A Defensive Rating of 98.0 is something Oklahoma City hasn't seen from any opponent in this postseason. Victor Wembanyama and De'Aaron Fox present matchup problems that can't be solved on a spreadsheet. If the Spurs can limit Shai Gilgeous-Alexander to difficult looks in Games 1 and 2 on the road, this series changes shape fast.
What It Means
The fact that the Audit Season model couldn't separate these two teams isn't a limitation of the formula — it's information. Two perfectly scored series-clinching games means you're watching two historically well-constructed rosters peaking at the same time.
OKC is the right pick. Their structural advantages are real and consistent. But this is not a series you watch for the outcome. You watch it for the chess match: whether San Antonio's defense can disrupt OKC's offensive system, and whether SGA can find cracks in a wall that gave up 98 points to a Minnesota team that had beaten Denver.
The numbers don't lie — but sometimes they tie. This is one of those times.
San Antonio's Defensive Rating in Game 6 was one of the best we've tracked this postseason. Can it hold for a full series against the most efficient offense in the West — or does SGA find a way to break it in Games 1 and 2 at home?
