The question I would ask for a team like OKC is, is what they are doing sustainable? Or replicable over a 7 game series. Because if the answer is no, then something needs to change, whether it's gameplan or a change in personnel. I don't want to keep harping on last year's team, but it was their major problem then and you could see it coming a mile away. Westbrook is unstoppable against the Nuggets on your typical Wednesday night but when it comes to the playoffs they got destroyed because trying to play a team like the Rockets or the Warriors the way they play is suicidal.
To me I look at this current team and the way they are comprised and I don't see a whole lot different. I disagree that the Warriors and Rockets would be scared of them in the playoffs. The Warriors know how to deal with Westbrook. The Rockets in their current state would blow OKC out of the water in a playoff series. OKC have a good starting defensive unit yes, but there is not enough there that would worry me if I was Kerr and D'Antoni.
Long story short is that Westbrook is not efficient enough offensively to be as ball-dominant as he is, and when he doesn't have the ball on offense he almost literally does nothing. Again I don't want to harp ad nauseum on last year but this harks back to then and what the coach and management let him get away with.
This all may be moot soon anyway as I don't think we're far away from a tipping point as far as their roster construction is concerned. This isn't like the Cavs where they can coast for half a year because you know they'll be right come playoff time. There is a small window here for OKC to make it work or they're back to square one. If it keeps going like this George will be gone (he may be gone anyway, but in any case I doubt he hangs around if the team is still playing like this in a few months time). Who knows with Anthony but I doubt he stays because OKC won't want to pay him. Then what do you have? Westbrook and Adams but without the supporting pieces you had to build with after Durant left.
