I see the 2 worst teams as clearly the Bulls and the Nets. All the others the OP listed either have way better coaching and cultures, or simply better rosters. But the Nets and Bulls will be terrible.
I definitely think there are tiers in those eight or nine teams, but I still think they're all pretty close. I think the Bulls, Nets, Hawks, and Pacers are the worst without context, but when you add in the fact that Sacramento and Phoenix are in the West, they get put into that group, too.
I think LA, NY (mainly Porzingis), and Orlando are the best three of that group, but it wouldn't surprise me at all to seen any of those three as a bottom three team at the end of the season.
