It would be surprising if Durant leaves this year, he must likely takes the one year deal and enters Free Agency with Russell.
It may be wise to sign someone to an Amir Johnson like contract and maintain flexibility for next year.
We could move Thomas if Russell and Durant came to Boston.
Durant Crowder
Bradley Smart
Westbrook Rozier
Not hard to build around that core, plus we still have the Nets pick hopefully Simmons if not Murray, Hield, or Poeltl.
