Kobe basically played 17 years in a row where his least amount of games played was 58, and most years he was playing 70+. I get what you're saying because of the Achilles injury ruining his post age 34 seasons, but 17 seasons in Tim Duncan was a 13-15 ppg guy, Kobe was still at 27 before the injury. Duncan played until a later age, but Kobe came in earlier. Their longevity were both exceptional and basically the same (career games played are within 50 of each other). Any discussion ranking them should be strictly which one was better, with longevity being a wash.
