Bull !!! This is absolute bull . Going back to back shows dominance. Winning a le here and there shows that the front office was good enough to make adjustments from previous years. But when you do it two, three, four times with the same team, then that shows the mental toughness of that team and it's leader. Duncan failed to even get back to even try to defend his le. The 80's Celtics were just as good as the Lakers, but Magic wanted it more than Bird. Slice it up however you want it, but Bird failed to defend his le.
In every sport, from boxing to tennis, and everything in between, defending your crown is the hardest thing to do, because everyone is giving you their best shot. Now you want to say it holds know weight in basketball because Kobe has mad a career of it? Get the out of here. Kobe going to the finals and winning the last two is a greater feat than anything Duncan has ever done. Not to mention the fact that he has a three-peat as well. Anyone can luck up and win a le. The Pistons are a perfect example in two situations. The lucked up in 89 when Magic and Scott went down and the swept a great Laker team. And they lucked up in 04 when Malone went down and they beat a great Laker team that had Kobe and Shaq feuding. The difference between those two Pistons teams was the 89 team came right back and showed it wasn't luck. The 04 team didn't.
