Since you obviously forgot, I will answer it for you.
There were two main forks in the argument, and I will lay it out for you, just because you are a Suns fan, and you seem to be a little slow.
1 - Duncan does not belong in the same breath as Lebron for anyone who is not a Spurs homer
Well, there are a few arguments against it, first and foremost being that the article we are quoting had them #7 and #8 all time, next to each other, so they MUST be in the same breath.
Then of course, Duncan put up impressive stats throughout his career. While they are not as impressive as Lebron's, they are most definitely in the same breath.
As expected, Lebron, being a wing player, had better FT%, 3P%, AST, STLS and PF numbers
Duncan, being a post player, had better FG%, REB, BLKS and TOV numbers.
Lebron has the edge on scoring, which really wasn't a surprise.
Duncan had a lifetime ORtg of 110 and DRTG of 96 with a difference of 14, Lebron had 116 and 102 for a difference of 14.
They had similar WS/48 numbers (.211 vs. .240) and Duncan had higher WS numbers due to him player more games (201.2 vs. 178.9). Duncan had better DBPM but James had way better OBPM, and the overall BPM goes to James (9.2 vs. 5.5, but then James hasn't played 8 years out of his prime yet). The numbers are similar in the playoffs.
From a cir stantial, subjective angle, Duncan led a team of young players and way over the hill vets to the 03 championship, putting up monster numbers in the process. That remained undoubtedly his finest year. Lebron's finest has to be 2012, where he put up monster numbers in the playoffs. That said, a supporting cast of Wade, Bosh and Allen is so much better than a last year Robinson, young Parker (replaced by Claxton in clutch moments), young Ginobili (out of control) and Stephen Jackson as your second best player.
They are on pretty even ground, there really isn't much to argue about than that by anyone other than you.
2 - Not having Kobe at a top 10 was based on arbitrary criteria
Well, it's certainly subjective, obviously, but was it arbitrary? I won't agree to it, and I have outlined it here and there multiple times in the forum, you have proven yourself to be extremely slow, so I will list this out one more time.
Most people's top 10 usually have the following list of players (more than 10)
In everybody's list:
Jordan
Magic
Bird
Kareem
Old Timers:
Wilt
Russell
Oscar
West
Depends on who you have
Hakeem
Duncan
Shaq
Moses
Kobe
Lebron
Dr. J
Out of these 14 players, Kobe is the only player who missed the playoffs in his prime AND never led his team in most advanced category in any of the championship season. You can say that he is really an exception, or that he doesn't belong to the group. It is a simple spot the difference exercise that most people learn to master by the time they are about 5, but you seem to have trouble with it.
I just chose to look at this, and say, Kobe can't be the only exception, the only conclusion is, Kobe is not a top 10 player.
Now compare to your criteria, which was losing in an embarrassing fashion (swept or lost to a lower seed) in every round of the playoffs.
Magic and Kareem:
1st round - Lost to the lower seeded Rockets in the 1st round, a team with a losing record to boost. They were the 6th seed but the 6th seed was the lowest seed to make the playoffs, so it is equivalent to 8
CSF: Magic Lost to lower seeded Suns in 90, kareem lost to lower seeded GSW in 73
CF: Lost to lower seed Rockets in 86
F: Swept in Finals by Philly in 83
to boot, Kareem missed the playoffs twice.
Using your criteria, Magic and Kareem couldn't make the top 10 either, so unless you throw out Magic and Kareem, Duncan stays.
Besides, Duncan never did that in the finals, so you just added on missed shots, and different cir stances.
But if you were to add in those cir stances, multiple players in the above list did too.
Lebron as I listed, had "embarrassing" moments in every round, so did Wilt, Kobe, Hakeem, and basically everyone not name Jordan. So your top 10 list is left with one person.
In other words, your criteria wasn't arbitrary, it was just , but you failed to realize it, and even tried to claim "victory".
My question to you is, were you born re ed, or did you make an effort be re ed? It's hard, really hard to be as shamelessly stupid like you.
