Wanted to inject this into the main thread:
http://www.basketball-reference.com/blog/?p=9840It's a pretty cool (although mostly limited in scope to box scores) WAR method. Plenty to discuss, but note the gap between Karl Malone and the field for their career value. (Obviously this overstates it a little because Malone never missed RS games while stars who missed 25 could still go in the PS).
As you can see, Malone is nearly 100 points ahead of No. 3, Hakeem Olajuwon. That's roughly the value of Paul Pierce's BEST SIX YEARS in this system.
The next thing to note is the 6-year consecutive prime of LeBron James. Again, this is not a definitive statement about player quality/worth, but to point out to people who really don't realize how many great seasons he's *already* had relative to the remaining players on our list. That's why I'm pretty comfortable with an easy James vote at 15. (Hard for me to twist up a Jerry West argument, but at least that's within reason bc of the era difference.)
