Joining the party late here, but the second three peat has some glaring issues. First off, each of those seasons there were three teams that finished with 60+ wins. You know how many times that's happened in the modern era (when Magic and Bird entered the league)? Five. Three of them were '96, '97, '98. The other two are 1981 (Bird's first championship) and '09 (Lebron on the Cavs, stacked Lakers, and stacked Celtics). Look at every season since Magic and Bird entered the league. Sometimes two teams would get 60, but there was a certain level of competitiveness that kept teams from reaching that 60-win level. The league was insanely diluted in the second three peat, and the Bulls were just stacked (best player ever, best perimeter defensive combo G-SF ever, best rebounder in Rodman, 6th Man of the Year, 3-pt shooter in Kerr, etc.) against the weakened competition. In '96, the Sonics won 64 games. Good enough to be the #1 overall in most seasons, and they finished 8 games behind. The Magic had 60 wins that year. Those are ridiculous win totals for a single season.
Overall, the fact Jordan never faced a dominant center in the Finals (and even the Eastern playoffs...cue the Ewing apologists) is kind of convenient. After the league added four teams in '88 and '89, they ripped off their first run, which lined up with the '80s teams crumbling with age/retirement.
I'm not saying it's not impressive, I'm just saying it needs a little more scrutiny.
