Well, I would say you have an overall good list but........... what about more players from the ABA like
Marvin Barnes
Warren Jabali
John Williamson
Zelmo Beaty
Mel Daniels
Ralph Simpson.....(India Arie's Dad...YES that INDIA ARIE)
Ron Boone
& Mo Lucas.
I would also have considered Norm Nixon..(very underrated), Bob Love.....(my favorite Bull of all-time) & Kiki Vandeweghe.
I would also have Artis Gilmore in the top 50 over Bob Lanier...( just a suggestion)
...also I'd switch Karl Malone & Kobe Bryant....... while you're at it... switch Olajuwon & Shaquille O'Neal.
I'm a Bulls fan, so naturally ..(at first) I thought you were crazy to put Duncan ahead of my man MJ, but I have to admit....other than an old David Robinson(twice).... he's won 4 rings with some scrubs....(including beating Shaq & Kobe twice in their prime to get those rings.) The amazing thing is that the if not for a stupid play by Manu Ginobili and that lucky .4 shot that shouldn't have counted..... the Spurs would have won 6, including 5 in a row. I'd still put Jordan ahead of Duncan, but that's only because I love the Bulls. Scottie Pippen was the real MVP of the 1998 NBA Finals, just as Duncan was the real MVP of the 2007 NBA Finals. Pippen & Jordan were neck and neck as to who was the best player on the team during those last 3 title years, however, it's no question who the Spurs best player is.
I didn't know this, but Duncan is the only player in league history to have made an All-NBA and All-Defensive team every year for the first 10 years of his career...... not Shaq, Wilt, Jabbar, Jordan, Bird, Magic, The Big O....none except Tim Duncan.
If the Spurs win two more titles with Duncan as the leader, he makes a strong case for greatest player of all-time. If they win 3 more...... Duncan will be the best to ever play.
He's still very boring to watch.
Overall, I like your list. I'm glad you recognize that any player who's among the top 10 scorers in the history of the game should be ranked pretty high. .....only Wilt, Jabbar, Jordan, Karl Malone and The Doctor have scored more points that the legendary Dan Issel.
on a scale of 1 to 10, I give your list a solid 9.
