When it comes to big men, Malone and Kareem have set the bar in terms of performing well late into their careers. He will turn 40 before the end of the season.

How much longer does Duncan have to perform at this level to pass them? He will turn 40 before the end of the season.

In my opinion he'll pass Malone at the end of the season, but for Kareem I think he needs one more.

Thoughts?
