Do you really need data for it? It’s common sense that Westbrook would be getting most of his triple-doubles against bad teams, and that those teams would give him the most leeway to run up his stats. As I’ve said, watching a large number of Thunder games will show that he has certain go-to moves he uses over and over again to maximize his assists and rebounds.
But I want to make sure: are you REALLY saying that you don’t believe Westbrook’s triple-doubles are mostly coming against bad teams, compared to the average team the Thunder are playing? Do you really need statistical evidence before you will accept that?
