for me i have always like KG's game compared to Duncan's and even try to emulate Kg's game when I would play ball, but Duncan is just on another level though. I have KG as the second best PF, so I don't think it's bad to be second to Duncan. But, whose game was better as a whole, you gotta give it to Kg and he is much more versatile, but Duncan on that block and low post in his prime is something else though. Also, if we are going with who had the better MVP year, you gotta go with KG. Eventhough Duncan gots 2, but KG in 04 was a beast and was one of the most underrated MVP's of the decade. The dude was getting 24, 13, 5 with 1.5 steals and 2 blocks while also shooting 50% and close to 80% at the line. That might be one of the GOAT and most versatile MVP's years I have seen and witnessed. Duncan has had the better career due to the rings, but if we just remove the ring argument the comparison is much more closer and more debatable.
