This is hindsight 20/20 of course but I think Harden should have been the centerpiece. He's best creator off the dribble they had. If Westbrook and/or Durant didn't agree with that, they could have moved one later on, but they should have kept Harden. I remember in 2011 against the Mavs that only Harden was executing pick-and-rolls properly among them. Once he left, their offense would usually crumble. I never expected him to become the scorer and shooter he has become, but his vision, patience, and passing ability were always elite for me.
