Why OKC's Finals Loss Wasn't a Sign of Decline, Per the Numbers
OKC finished 64-18 with a league-best scoring margin, and an opponent-adjusted breakdown shows the Finals loss to San Antonio was a defensive letdown against one team, not a broader slide.

Asked: Did OKC get worse?
No — OKC's season didn't decline. The Finals loss was a defensive letdown against one team, not a broader slide
Oklahoma City finished 64-18, first in the league by record, with a full-season scoring margin of +10.53 points per game — and the team's own sustainability read confirms that wasn't puffed up by luck: their actual win rate (.781) is right in line with what their scoring margins support (.797 implied), a gap of essentially nothing. This was a legitimately dominant season, not one riding variance.
What actually happened is narrower: OKC lost the Finals to San Antonio in six games, and the losing stretch was overwhelmingly a defensive issue, not an offensive collapse.
| Window | Games | Record | Scored/g | Allowed/g | Margin/g | Opponent strength (opp win%) |
|---|---|---|---|---|---|---|
| Last 5 (Finals) | 5 | 2-3 | 105.2 | 110.8 | -5.6 | .756 |
| Last 10 (playoffs) | 10 | 6-4 | 113.4 | 111.4 | +2.0 | .723 |
| Last 20 (reg. + playoffs) | 20 | 14-6 | 117.0 | 109.8 | +7.2 | .635 |
| Full season | 97 | 75-22 | 118.5 | 108.0 | +10.5 | .526 |
Margin trended down as the competition got tougher, which is expected — the opponents in that final stretch had a season win rate nearly 23 points higher than the average team OKC faced all year. Adjusting for exactly who they were playing tells the real story:
- Offense held up fine. OKC scored 105.2 a game against San Antonio, which actually came in 2.2 points above what the Spurs' defense was allowing coming into the series (103.0). The raw drop from their prior 10-game average (120.7) was almost entirely San Antonio being a good defense, not OKC scoring worse than it should have.
- Defense is where it slipped. OKC allowed 110.8 a game, which is 4.8 points more than San Antonio was scoring on average coming into the series (106.0). That's the real deviation — the Thunder let a good-but-not-historic offense play well above its own level for six games.
So the finding isn't "OKC got worse," it's "OKC's defense had a bad series against a specific opponent while everything else about their season — record, margin, and the process behind it — was as strong as any team's in the league." The team's power rating, carried into the offseason at +7.0 points versus an average opponent (last computed September 2, moderate confidence since it's an offseason carryover), still reflects that.
One real question mark for next season, separate from any in-season decline: OKC has already lost real rotation scoring since this roster was assembled — Isaiah Joe (11.1 ppg), Aaron Wiggins (9.4), Luguentz Dort (8.3) and others are no longer with the team, replaced on the roster by unproven additions with no NBA scoring line yet. That's roster turnover to watch entering the season, not evidence of decline in what already happened.
Confidence: High on the "didn't get worse" read for the season and playoff run — it's built on the full-season record, the sustainability model, and an opponent-adjusted breakdown of the exact losing stretch. Lower confidence on how the roster turnover nets out for next season, since none of those new pieces have played a game for OKC yet.
