It's has nothing to do with me or my opinions, I'm certain because I've seen the results of this type of management before and I can see what is happening now. If the team were winning, all things good in the locker room, and players performing to expectation levels then it would be a different story. It would also be shirking historical basis if it lasted for any significant amount of time even under those ideal conditions. Good moments will still happen from time to time, but it's not a way to go about roster management ever, let alone at the start of a rebuild.
Second guessing heart is too simple. No player makes it to the NBA if they have no heart or talent. It's the same reason why some players get to Sacramento all of a sudden "suck" then move on to a better situation for their game and unbelievably reappear. Role is almost everything in the NBA and when you have a team mostly comprised of young scoring talent it could severely damage careers if not handled properly. That's not good for the Kings because they are in the midst of a rebuild where they are losing value on almost every asset they have at the same time.
George Karl had his own issues but platooning wasn't it. Look at his minutes distribution under per game:

Now look at Joegers:

Playing players in the low to mid 20's on average as opposed to having some players getting real starters minutes makes a huge difference to players. Not only that but stability on the floor as well. George Karls issue was putting in a bad fit system around his talent. Right now Joerger is not only doing that but he's also cutting off players abilities to solidify themselves in a true starters role.
Now the specific instance recently that I can recall mirroring this and eventually having the same results is also the same circumstance that allowed the Kings to trade for Bonzi Wells. The Mike Fratello helmed Grizzlies in 2005-2006. Look at their minutes distribution chart:

The per game chart doesn't even look as bad as the Kings! The team was still winning but the staggered rotation patterns and lack of major minutes caused a revolt. The answer for Fratello to save his own hide was to go the total opposite route after iirc Gasol started to pipe up. Next year Gasol played 39 minutes a game. Fratello was a Hubie Brown disciple that took over for Brown who was also known for his platooning strategy. It's a style of coaching that historically works at the college level and sinks the ship in the NBA. The Grizz held on for a few years doing it, but they were winning and experienced. The Kings are not, it's showing, and the end result will hurt twice as bad in the end.
