Reports were at least that Rondo wanted him to stay, no?
That's part of it, maybe.
Rondo likes the freedom he gets. Rondo has said that coach (i.e.e freedom) would be one of the factors in his FA decisions this summer. Rondo as recentyl as a few days ago declined to point fingers at George's schemes.
Then again Rondo mentioned the optional shootarounds...unless maybe that was aimed at a lack of dedication from the players? And now there is even pushback about whether the 3 or 4 players showing up was accurate.
Then you have Cuz, who various people like to tag with a variety of inaccurate labels, few less accurate than coach killer. In his entire time in Sacramento you know how many coaches Cousins has asked us to fire, so far as we know? None. Zero. Paul Westphal absolutely hated him and more or less quit over it. Fired himself. Smart and Cuz clashed, but Smart's fate was sealed by the change in ownership, he was fired before we even officially decided to keep Cuz. Cuz in no way shape or form wanted to lose Malone. And Cuz even advocated keeping Ty Corbin because he didn't think he was being treated fairly. When Karl tried to backstab him this summer, Cuz's response was to ask for a trade behind the scenes, not to ask for Karl to be fired.
Then early int he season after Cuz blew up at him the stories went (and these stories are form some of the same sources that got this Karl being fired thing wrong, so grain of salt), but still, the stories went that Vlade may even have asked Cuz and Cuz said don't fire him.
Now I don't have a great way to explain the last two games if Cuz didn't think Karl was being fired unless it is the normal Cuz shutting down when it all goes to crap thing. Because I think Cuz desperately wants to have stability and a long term coach. And maybe his crap play was him hearing and anticipating the end rather than him trying to cause it.
And so again, Vivek could have meddled for money or ideology, Vlade could have balked because of stability and a certain over-respect for old guys he knows, or quite possibly the lead players might still, in spite of everything, prefer to keep waddling along under old George rather than be cast into uncertainty again. Or some combination of the above.
