I agree with your top 3. I disagree with everything after that. For me rn it's....
Tier 1 (solidified as contenders)
Lakers
Bucks
Clippers
Tier 2A (ceiling of tier 1 but minor flaw)
Jazz, flaw: inconsistency
Tier 2B (ceiling of tier 1 but significant flaws)
Celtics, flaw: bigs
Raptors, flaw: offensive creation
Heat, flaw: experience, offensive creation in a playoff setting
Tier 3 (Longshots with bigger flaws)
Rockets, flaw: Defense, gimmick scheme
Pacers, flaw: Offense
Nuggets, flaw: No second/third star, offensive creation in a playoff setting
76ers, flaw: Roster makeup, spacing
Mavs, flaw: Defense, experience
