If I'm OKC
I demand either Kemba or Gerald Henderson along with the number 2 pick other wise I wouldnt do it.
They need bench scoring with Harden leaving. If they can get Henderson, I say they take a chance on Thomas Robinson or Drummond. They wont need Beal or MKD. Perkins is not the answer at Center. He could teach Drummond and hopefully he will turn into a star instead of a bust.
If they cant do this, I wouldnt do it. Beal and MKD will never be Harden. I would just keep Harden for another year.
