I suppose it is possible. I don't believe that Durant is leaving OKC this season but who knows. I think Howard is a clown but he is a more mature clown than he used to be. Durant might be the perfect Alpha to pair him with. We would still be weak at PF (pencil in Amir for now) but with Howard at Center, we would have more flexibility to fill that in.
Howard
Amir
Durant
Bradley
Thomas
Bench: Smart (PG/SG), Rozier (PG), Young (SG/SF), Crowder (SG/SF/PF), Jerebko (PF), Olynyk (PF/C), Mickey (PF/C).
I like all the multi-positional players we would have on the bench. Lots of flexibility for match-ups or addressing injuries.
Plus, because these are free agents, we get to keep our picks (although not sure what we do with them all).
I would be very happy with this. I think this team would do very well. It could even give Cleveland a run I believe.
So try to sign Howard this year and hope Durant comes over next season? i could see Danny taking this kind of multi-step approach. Get Howard now while we can and hope it leads to Durant down the road. If it doesn't, and assuming we have signed Howard to a trade-able contract, just trade Howard and go back to building around young draft picks.
