During that time those players are still very young and inexperience. The likes of Durant, Harden and Westbrook was good to watch, but they are still green. And by the time most of the players, left, their career blossom. But just imagine if those three players was at their peak, they could have been unstoppable.

They really need to rebuild now, Westbrook did everything he could, specially after Durant left. But it seems he can't accomplished it. So it's time for him to be traded and OKC needs to find new set of players now.
