Durant shot over 40% on 3's this year, 39% last year, while still shooting over 50% overall. That's very, very, very efficient offense. That is not something you point at and say "that's a problem".
Westbrook, OTOH, shot slightly under 30% on 3's, and 42.6% overall. Westbrook is a freak of nature, and it's a fine line between stifling his greatness and getting him to just tone it down a bit, but we're talking about a whole lot of OKC possessions that end with a Westbrook brick.
As to this general thread, I have 2 lines of thought here. One is that the next guy in OKC could be Steve Kerr. Mark Jackson looked, on paper, like he was doing a great job. And the players mostly liked him. Clearly, though, there was room for improvement, which Kerr proved rather emphatically.
My other line of thought is that the OKC job and general situation might not be quite as good as they look on paper. You can view Westbrook and Durant as 2 great, but slightly mismatched pieces. You can look at Ibaka and wonder is he's ever going to be more than just a jump-shooting big guy who plays nice D. You can wonder how Kanter is going to fit into a fully healthy OKC roster, specifically because he's a truly terrible defensive player. In other words, OKC might just be the classic case where a lot of really shiny parts don't add up to a great whole.
