I am skeptical that the league concern matches what is happening in podcast/twitter land, but who knows for sure. I don't doubt that OKC is complaining, they are min maxers. But the idea of the league being so focused on the Jazz when they are going to exceed their over/under by 10 wins feels far fetched for a multitude of reasons.
I mostly agree and if you look at my posts from last year I argued with a lot of people along the same lines. I think the league mostly cares about maximizing profit, but I do think the league cares about their reputation and as the noise gets louder I can see them taking more drastic measures than they did last year.
