Whatever the result is, the article is just stupidity in it's purest form. Duncan get more points per season than Shaq not because he's a better scorer, it's because Shaq is further removed from his prime. The same pretty much applies to all the stats.
The article did nothing to normalize pace, minutes played, the way teams defend either of them, what kind of teammates they have, and basically look at the stats on face value.
The blocks and steals department means absolutely nothing with regards to defense, and the writer tried to pass it off as some kind of gauge to defense.
Duncan, as good a passer as he was, was not as good as Shaq during the majority of their careers. Duncan is an absolutely fantastic big man passer now, and he has reached this level around probably 2005, 2006 or so, but Shaq has been a great passing big man since his Orlando days. The assists numbers are misleading based on the kind of offense teams run around Duncan and Shaq.
