Why should he stay? OKC isn't getting any better, they aren't the high seed and their team isn't getting more help, they have to overachive to get in the semifinal, let alone to win the final
And why should he wait for RW? they can still play together in another team if they really want to
If i am KD i will sign 1+1 with Celtics to see if this is what i want, in this case the financial situation is actually in our favor
