I feel like Bill Russell was the Rondo of the center position in his era. Hands down the best defender at his position, and able to leave his mark on the game without scoring, but unable to be called the greatest because he doesnt have an all around game.
Basketball goes 2 ways, and if you aren't capable of dominating both sides, then you aren't capable of being the greatest ever. I'm way to young to have watched Russell play to know for sure, but looking at his stats, it doesn't look like he was THAT great on the offensive end. I grew up watching Jordan, and it seemed like he had the ability to choose how he crushed a team...offensively with his scoring (inside+out), or defensively (lock up man on man, or harassing the passing lanes).
Russell=greatest winner in league history
Jordan = greatest player
