Who has had the largest impact in NBA history?

all you guys are wrong. Julius erving,larry bird,magic johnson all helped saved the NBA,WHICH WOULD NT BE HERE RIGHT NOW! BECAUSE IT WAS GOING UNDER!commissioner stern then was able to save the league with a couple shrewed tv deals including one year there was only six televised nationally broad casted games.as for jordan,all you have to do is read the jordan rules,your opinion will change very fast. as the late great (goat) wilt Chamberlain was once quoted: if anything the rules were changed to make him better.now when they put rules in the game to stop you,then you can come back to me with he is the greatest of all time stuff! don't get me wrong,jordan is great,but there are at lease 3 other players who i would put in front of him.Chamberlain,jab bar and Olajuwon
