imo different era's means you really cannot compare them, however, in my opinion, the bulls from the early 90's would beat - all- the teams that lebron has been on they would beat the warriors too.
hell the lakers and celtics from the arly/mid 80's would too.
as for GOAT , again different era's= different playing styles
60's - Russell hands DOWN.
70's not sure
80's magic & bird the rivalry between the two was Awesome to watch esp in the finals
90's Jordan
2010's Lebron
one on one...that would be good- each player in his prime?
depends on the style of game they played. down low near the basket, Russell would destroy all the others...
mixed gameplay, imo , jordan first russell last(outside shot accuracy),,, and it depends on the style of games for the others- pure range shot, imo bird was better than the rest in that regard. you have to remember back when jordan bird and magic played, the 3 pointer was in its infancy...with how dominating it is in todays game play, bird would have been a 3 point maniac in todays game play style.
