Again, let's be clear what we are discussing. It is the entire body of work over a career, not a player's 2-year prime. And since you want to use stats, let me throw up a few more.
Career PER: Hakeem's career PER is lower than the people he is compared against:
http://www.basketball-reference.com/...ER_career.html
The top 10 includes Shaq, Robinson, Wilt, Tim, Kareem, Pet , Barkley. Hakeem is # 16.
How about Single-season PER:
http://www.basketball-reference.com/...ER_season.html
Hakeem's name appears twice on that list (#57 and #97).
Duncan appears 5 times (# 63, # 64, #66, #69, #93)
Shaq appears 11 times, DRob appears 7 times, Kareem 7 times, Wilt 8 times, Pet 4 times, Malone 6 times, Barkley 4 times.
Curious, because if Hakeem had bad teammates after the drug suspensions, you would expect him to put up the numbers (a-la McGrady's 30+ PER when on the Orlando Magic).
Hakeem's consistency and dominance are blown out of proportion because he had 2 great post-seasons (which might have been laid waste if Jordan hadn't left basketball). He was the leader of mediocre teams for the most part of his career.
Whereas Duncan won a le with Stephen Jackson as the 2nd threat, won 60+ games with Derek Anderson as the 2nd banana, led the Spurs to the highest win% in all of professional sports in the entire last decade, etc.
When it comes to career consistency, Hakeem is not even in the same ballpark as the other great big men across eras.
