I watched a fair amount of basicball in the 80s. Centers didn't get as much credit as some of the more visible positions. He was one of the best at that position, but positions seemed more formalized back then (I rarely remember centers dribbling up the court). Also Kareem was on a team with another superstar who overshadowed him.
The great basketball teams even with their stars required really solid support players in the other roles. They all were pretty good.
Many less 3 pointers (I think Kareem made 1 his entire career). The scoring record seems a lot like a career longevity thing, I don't think I've heard it talked about alot.
As he states in the article, Kareem was very competitive and fairly serious. Basket ball had some real characters (Rodman, Barkley) As a celtics fan, his skyhook shot he developed was really hard to defend against. Against the celtics McHale had a sort of half hook, but it wasn't like that. I remember with friends trying to do that skyhook on the court.
He seems to have that wisdom now that comes with age.
