Duncan is the reason for that stability. He's made sacrifices for the franchise to be stabilized. Kobe could've had the same thing but why be jealous. He won his way and Duncan won his way. All this losing is making Kobe weak. At the end if the of the day they both have the same amount of rings but Kobe has made done it his way and made more doing it.
If I had to choose which career is easily choose Kobe's over Duncan. Better bytch, better location, less sacrifice, and more money. Kobe is also more popular making him a bigger icon.
