Duncan played an extra year, that means more development and more time to achieve things. Second, he never won a title like Kemba did, let alone the fact that Kemba put an entire team on his back and won it all, something that can be seldom said. Finally, Kemba's numbers as a junior were pretty ridiculous too, dont remember off the top of my head but id certainly say its not overshadowed by Duncan's 21-15-3 in any way. I get that Duncan was super consistent and well rounded, but Kemba's peaks were something else. Kemba could win you a game that mattered, Duncan and big men in general cant really do that.
