In my angry drunk outing last night I met up with someone who works for the Suns in their media, quite a bit of access. I don't ask him about inner workings stuff because it's a douchy thing to do and he wouldn't and shouldn't say anything anyway.
But... last night the filter was off for him.
He says 100% Vogel is fired within hours of the Suns getting eliminated (not a surprise but nice to hear).
He also thinks Durant is uncoachable. Durant doesn't want to play in a system, he wants to go out there and "hoop". Take guys one on one, he passes up on open catch and shoot 3 opportunities in favor of trying to beat a guy off the dribble or with a fadeaway. His ability to make tough shots is supposed to be a safety blanket when the offense can't make a play but he uses it as his primary option.
Also, and this has been discussed here plenty, that Booker used to get pissed about loses has totally changed with the subtraction of Paul and the addition of Durant. Durant has rubbed off on him in all the wrong ways.
