After the Sacramento Kings failed to make any big moves at the trade deadline, many fans were upset. Honestly, they should be happy that the Kings didn't trade for Ja Morant. He would have taken a bad situation in Sacramento and made it a 1000 times worse. Avoiding him was the right move.
Sacramento is in the early stages of a massive team rebuild project headed up by general manager Scott Perry. The main obstacles to that rebuild are the contracts of Domantas Sabonis, Zach LaVine, and DeMar DeRozan, whom the Kings have not been able to trade so far.
The reality is that they are big-money deals for players who aren't worth those kinds of numbers to other teams. Until some more time and dollars tick down, the Kings are not moving any of them. In the meantime, Sacramento will continue to make the moves they can while building to the next episode.
That doesn't change the fact that the fans wanted to see more from the Kings at the trade deadline. But the only moves to be made would have set the process back, such as sending maybe Sabonis to Memphis in exchange for Ja Morant. And nobody wanted that to happen.
Ja Morant would have blown up what's left of the Kings
To be honest, picking up Sabonis actually would have been a good move for the Grizzlies. They are in a good position to run their offense through Domas, which is how you put him to good use. Plus, he's an impressive rebounder. Even better, Domantas is an actual adult and lives his life like one.
On the other hand, Morant is not. Despite his talent and skill, his off-court antics, constant injuries, and disturbing levels of arrogance have turned his brand in the NBA absolutely radioactive. The Grizzlies were open to trading him, but there was even less interest in Ja than LaVine got.
The main reason Sabonis and LaVine garnered few offers is purely cost. They have two of the worst contracts in the league. Morant is also expensive, but front offices are afraid of him tearing their teams apart with his seemingly endless nonsense. That likely includes the Kings.
If they had traded for Morant, he would have destroyed any progress Sacramento has made. Beyond that, his massive contract would have prevented further moves, and he would have been even more untradeable. That's definitely a worse scenario than what didn't happen at the trade deadline.
