While we are talking about NBA greats, let's mention Phil Jackson. The guy has more rings than fingers: two as a player, eleven as a coach.
Just looking at the second three-peat: Yeah, he had Jordan, Pippen, and Rodman on the second three-peat, but he built a dominant team with Luc f'n Longley as the center. He had an underrated Ron Harper handling the ball and d'ing up the ball handler, so Jordan could conserve energy. He had a creative bench which feature Kukoc as the sixth man of the year and Kerr as a money 3-point specialist. While Rodman seems like a no-brainer now, he was pulled in from the Spurs after being cited as a problem child and scapegoated for their failures in the post season. And sure, Rodman was/is a nutcase, but Jackson got great production out of him. I don't know what my dream NBA team looks like, but Jackson is certainly the coach.
