I think the Christie bump is a mixture of two things. One, the team has deviated back toward the norm as far as clutch time play has gone. Two, Christie has pumped some life into the team through his personality.
Mike Brown didn't tell Fox to jump right into Ivey on that 3pt shot or for DDR to completely flub the catch on that easy game winning dunk. He didn't cause Huerter and Keegan to shoot sub 30% from 3. That was just downright bad coaching luck. He did however have a hand in digging his own grave by not playing Keon. Maybe the Kings wouldn't even be in those situations if Keon had played 25mpg regularly? I can't comment on whether or not he lost the locker room or not but it does sound like things were a little complicated from the snippets we've heard from players.
Time will tell with Christie. We really have next to no insight on how the players are really coached. Even Shaq, Chuck and Kenny argued about how important coaching is. Shaq argued it wasn't important and Kenny argued it was and that Shaq is a one of a kind player that could dominate no matter who was coaching. Christie has gone on record saying "I can't teach you guys how to play basketball". I took that as him saying he can't go tell Sabonis, Fox and DDR how to play because they're all vets that know what they're doing. The question will be if he can help develop the younger players like Carter into the savvy old vets that don't need much coaching anymore. He can't answer that any time soon.
I've been pounding the drum all season that this Kings team is better than their record, and that a combination of uncharacteristically poor team-wide shooting, assorted injuries, and bad luck/bad timing in the clutch were the most likely contributors to the Kings sub-.500 record as they plummeted down the standings at the end of 2024. Their net rating has been pretty consistent all season long, and it suggests a team with talent enough to be maybe 4-5 games over .500, which is hardly world-beating, but also isn't anything to sneeze at in a tough Western Conference, and it could very well be enough to get you
above the play-in break.
All of that said, some progression-to-the-mean was to be expected no matter who's head coaching from the Kings bench. We're seeing that in their clutch play of late, we're seeing it with Keegan's outside shooting, with Monk's elevated play, etc. I do think that there were some decisions made by Mike Brown that surely compounded the problems the Kings were experiencing, so he may very well have been a defensive scheme adjustment or 20-25 mpg of Keon Ellis in the rotation away from keeping his job. But when you lose five straight winnable games at home in a tight Western Conference where a .500 record may not keep you in the play-in mix, then accountability becomes paramount. Should it fall at the head coach's feet? I dunno. From where we're sitting now, with the Kings back in the playoff hunt, it's hard to say that Monte/Vivek made the wrong decision.
Perhaps Christie's motivational tactics and his simplification of the Kings' schemes were enough to help their progression-to-the-mean along. But I think it's just been such a bizarre season so far that it would be folly to ascribe too much credit for the Kings' failures or successes to any one factor.
