I also have that same opinion about Celtics, they don't need KD, the only thing that they needed to do is to continue doing more progress with their system, they've made it to the finals last season the players deserves kudos for doing their roles and now they will again try to push for another shot in chasing the world title, having KD and breaking the good chemistry might not be a good idea for the Celtics' managements.
However, Boston Celtics show interest in Kevin Durant and even consider putting Jaylen Brown on the trade package.
It means the Celtics are willing to break their core just to get Durant even though Jaylen Brown was a big piece during their last Finals run. But since the Brooklyn Nets want more big fish aside from Jaylen Brown, that ends the story now, or...
I'm now even more concerned about Jaylen Brown. Even though NBA is business and players must accept that they might be shipped away even how valuable they are on the team, it gives Brown a disappointment that the team who thinks he values him is willing to just trade him away easily without even considering. I hope that won't affect his performance on the team which I doubt it really will.
