The NBA is a league rich in history, made all the more rich by unique teams scattered throughout its existence.
Some have won titles, others provided tremendous entertainment, all left NBA fans with unforgettable highlights. In certain cases, there are contemporary teams that harken back to the teams of yesteryear.
Bear in mind, there is no perfect comparison, nor are these intended to be such. These are teams that are reminiscent, not duplications. They have aspects to them that call to mind the teams from the past.
Also, these are based on my observations, which only go back to the late '70s, when I was 10 and fell in love with the game. They are entirely subjective. There may be other, and better, comparisons out there, but I can’t remember what I didn’t see.
The rankings are based on the affinity the present teams share with their historic counterparts.
