The situation he finds himself now in, is all his own doing.
He wanted this.
He's had first-hand experience of what it's like to exist on a stage that is based entirely on the material of ISO, with no winning-culture and a lack of accountability. He went through it with Westbrook and OKC. It's the reason why he went to GS; he then experienced what it was like playing for a winning organization and enjoyed all the spoils that came with it. He experienced both ends of the spectrum, of what it takes to win and what doesn't.
Yet he grew tired of playing in that [winning] system, almost sabotaging a title run in the process because he wanted to do things his own way. It's why he left and wanted to create something for himself.
Where now he finds himself in the same situation in BK, that he was in OKC: alongside a sidekick who's answerable to only himself, living and dying by ISO, feeling what it's like to seemingly have control over your surroundings, and only realizing after it's late that you don't have any control, at all; with your fate left up to the Basketball Gods who made you the protagonist in your own cautionary tale (that you lived and barely survived the first time around).
He wanted this.
His career path has taken the course of being stuck in a burning building, only to be rescued and resuscitated after being on death's door, only to willingly run into another burning building.
Unfortunately for him, it doesn't look like anyone's coming to his rescue this time.
