^ anything less than championship is a failure
Purely I think it had been in place to move on probably with how everything had been seeing the point that frustration had set in.
Now IMHO, it's fair for one to think that he wants to win a championship so with the deal my thought could be IF he does win one with Golden State, he could move on for another team
In the end, Cleveland can forget the Decision for a championship while Durant can at least rid of chasing one with an already powerful team although they will be losing rights to Ezeli and probably trading Bogut (from reports)
