Pitting teams from different eras will be a never ending debate, much like politics and religion.
Bill Russell said he never engages in such talk because it's like playing against a ghost. He said he would always play and go up against the guy who shows up in court.

Incidentally, my kid and I played and his team (Miami) beat me ( Bulls ) by 9 points
