In all honesty Pjax or McMillan would probably be best suited for this team. We don't have good pick and roll players, nor do we have guys above 6'4 that can spot up for 3s in transition. D'Antoni would work if you want a lineup of Brooks/IT/Jimmer/MT on the floor at the same time. Anyone else would just be bricking transition 3s in his offense.
I doubt that Kings fans would want Jackson though. Also, interesting comment by Barkley - he feels that Jackson lost some of his drive and intensity after overtaking Auerbach.
Smart says all the right things (most of the time), and to his credit he's got the team playing defense. I'm just not sure that he has the guts to force guys into more structure, not playing certain guys and making sure the team knows the shot hierarchy that should exist. That works to his advantage in connecting with them and building team chemistry, but not so much as far as winning goes. Smart would make a very very excellent assistant coach in my mind, at least until he proves that he's at least better than Westphal was.
