You mean the published list or the real list?
Paul Arizin, Bill Walton and James Worthy don't belong on the list. Bernard King was about twelve times better than Arizin. Bob Lanier had a far more productive career than Walton. Connie Hawkins was better than Worthy.
And of course, active players or guys who came into the league after 1996 weren't considered, so others have to come off to make room for Garnett, Duncan, Bryant and James (just to name four).
