The Cs are suddenly pretty flush at the 4, with Horford (in spots), JJ (better than Olynyk?), Crowder (in spots), and Johnson (in spots) as vets, plus Yabu, Bentil and Zizic recently drafted. There's also a few interesting FA options out there, including A Randolph.
If the Cs trade for a PF like Griffin, I think it's a given KO goes in the deal. But even if they traded for Cousins or Westbrook, I still think he's the first rookie contract in the deal.
I also believe that if they trade for a 'star' they'll reluctantly let Smart go over trading the Nets 2017 pick.
