Yes only because I couldn't find the 'When I Say Best Ever .... I Mean From The Mid-1980's Thread'.
Phil Jackson when asked by Time if he could take any player who he would he take ....
"In my estimation, the guy that has to be there would be Bill Russell. He has won 11 championships as a player," Jackson said in an interview with Time. "That's really the idea of what excellence is, when you win championships."

Russell did whatever was necessary to win, and unlike when Jordan was playing ....there was not the shithouse expansion teams to beat up on.
Wilt maybe even give Jordan a run for 2nd but like in the Aussie Rules and cricket ....there are clear number ones - only the dumb and the young don't know it.
You can make an argument for someone being a number 1, but how can someone be a clear number 1 when if put to the vote he would get about 10-20% of the vote?
Did you see Russel play?
Also there is a difference between best player and the player you would start a team around.
