I understand what you saying but this is a semi-bad example
MJ is self explanatory hence he is the GOAT. But Magic and Karem have only had 1 year they successfully defended a title(88) the rest were them doing it every other year like Duncan.
i understand repeating is important. But I wouldnt use it to hold so much weight that a lone successful title run is what so hugely seperates Magic/kareem from TD. When in terms of chips and how they won them. Magic/Kareem are more like TD than MJ
Let's also point out that that ONE title defense was at the end of Kareem's career when he was nothing more than a role player. And they went down to Game 7 twice in a row that year and were bailed out by huge Worthy games both times.
The idea that Kareem's greatness is defined by a game (Game 7 of the '88 Finals) in which he went 2-7 with 4 points and 5 fouls is why this is a stupid, stupid narrative.
Earv and Cap played against legendary teams in the Finals. 83 Sixers, 80s Celts, and the Bad Boys
So? They had two of the five greatest ever and multiple other HOFers, when did they actually beat a team that was favored over them? Ridiculous that we can make excuses for Magic/Kareem not repeating in their prime, but Duncan doesn't get those excuses.
Duncan doesn't repeat despite a monster 41-16-6 game with 6 blocks in Game 7 because Manu fukked up and fouled Dirk on a made shot, allowing him to tie the game.
Duncan didn't repeat another time despite a huge 30 and 16 game because Kawhi and Manu missed free throws and then Ray Allen hit that shot.
Kareem repeated despite a terrible 4-3-2 game with 5 fouls in Game 7 because Worthy went off for 36-16-10.
Somehow those are now the defining moments that make Kareem better than Duncan.
