Sorry to say this, but I think Kareem really needs to be the center. 23.4 points in 33 mpg at 38 years old. Still was averaging 15/6 at 40.
I guess now that I think of the aging gracefully criteria, it depends how you look at it with Kareem. He accepted 2nd fiddle and he was still a force at an age when most are done, but the graceful aging re: personality -- not sure about that.
