“The Basketball 100” is the definitive ranking of the 100 greatest NBA players of all time from The Athletic’s team of award-winning writers and analysts, including veteran columnists David Aldridge and John Hollinger. This excerpt is reprinted from the book, which also features a foreword by Hall of Famer Charles Barkley.

How do you rank the greatest players in history?

With great difficulty, would be my answer. Attempting to rank the best players in history from one to 100 for this book was impossible, especially when asked to compare between different roles, different positions, and different eras. How the heck are we supposed to split hairs between Ricky Barry and Dwyane Wade, the 26th- and 27th-ranked players on The Athletic’s list?

Well, that’s where data can help us. Or at least, if we use it well, it can help refine and improve our thought process for making the list. There is no ultimate truth here, no one correct and final answer. But for a sport that has been uniquely awful at preserving and discussing its history, it seems that developing a framework for the discussion might be a good place to start.

So how do we make a list of the best players of all time? There are some questions that I think should guide this. That perhaps, if pondered more deeply, might produce a bit less of the reflexive leaning toward secondary players on great teams that has plagued most “best-of” historical lists I’ve seen, including those by the league.

Let’s start here: If we’re covering more than 75 years worth of players, more or less, and only naming 100, that’s basically only one player a year. I get that most good players play for 10 to 20 years, but still, their prime seasons don’t encompass that whole span. (Except LeBron, you freak.) Only three players in history have been First Team All-NBA more than 10 times; only 20 did it more than five times.

Do the math: split 100 half-decade-long “peak primes” across 75 years and you get fewer than seven players a year; do the same with a decade-long prime and you get three. Any way you slice it, the bar for this list is pretty darned high.

Work backward, and one of the first gates for considering somebody for the top-100 list is: was this guy ever considered one of the 10 best players in the league?

That’s just the cover charge to get in the door. To really crack the list, you probably want to answer yes to the next question. Was this guy ever considered one of the five best players? It’s amazing how many players made the NBA’s list for whom those questions are, at best, iffy.

Or look at it another way: through the 2022–23 season, 72 players had made First Team All-NBA at least twice. That includes virtually all of the shoo-in types on the top 100, as well as some great players who didn’t quite make the list (it also includes Max Zaslofsky and Bob Feerick, but I digress).

Those two questions above are not the only valid ones, of course. There are a lot of related questions that should be part of the discussion, especially if we’re ranking players from one to 100.

In particular, if we’re talking about the cream of the cream, I would propose the following outline of important questions. (This cribs heavily from Bill James’s work in the 1985 Baseball Abstract, a dog-eared copy of which still lines my office bookshelf.)

• Was he the best player in the league? Did anyone, at any point, suggest that he might be the best player in the league?
• Did he win MVP? Did he factor heavily in MVP races?
• Was he the best player in the league at his position?
• Was he ever voted First Team All-NBA?

What about Second Team?

• How many All-NBA–caliber seasons did he have?
• Was he the best player on his team?
• If he wasn’t the best player on his team, was he at least the second-best player on a team with a clear all-time great as the best player?
• Was he ever the best player on a champion? Is it likely that this player could be the best player on a championship team?
• Did he have a major impact on the postseason, beyond just lucking into being on the same team as Magic Johnson or LeBron James? Did he have a greater impact on games played at the highest level?
• Was he good enough to be an impact player past his prime or was his career over at 30?
• How many All-Star–caliber seasons did he have?
• Was he a fixture on the All-Star team? And, um, not because of fan voting?
• Do players with similar advanced stats get consideration in the top 100?
• Is there any evidence that he was significantly better or worse than his stats?
• Is there evidence that he was significantly better or worse than contemporaries voted in awards?

As a 16th item, I’ll note that we should value the opinion of the contemporaries who were watching these players in the ’60s, ’70s, and ’80s, when most of us couldn’t . . . either because we weren’t alive yet or because the games were only televised locally, if at all. Additionally, the statistical record from this era just isn’t nearly as complete. Like it or not, the eye test matters quite a bit for that era.

You might look at these questions and think, know what would be great? It would be cool if someone had a formula to weigh these accomplishments and rank players by where they stood. Well, funny you should ask. In the process of making my own list for The Athletic’s Basketball 100 project, I developed a formula to help guide my process.

That formula is called GOAT points, which stands for . . . Greatest Of All Time, duh. I don’t have some funky alternative abbreviation, sorry, nor have I found an obscure backup center to name this after. (Someday I will create a formula called “SMREK.” Someday . . . )

Again, we’re trying to divine the players who succeeded at the highest levels and separate them from the ones who were merely very good players for a long time. Because of that, the highest-value achievements are orders of magnitude more important than more common accomplishments (like making the All-Star team or Third Team All-NBA) that in any other company might be very impressive.

GOAT points is a cumulative points system that adds up all the “quality” from a player’s career. In that way, it rewards longevity, but not at the expense of excellence. Bill Walton’s 1976–77 and 1977–78 seasons are worth more than a lot of players’ entire careers.

Here’s the system:

MVP vote shares: 50 points for each 1.0

Basketball-reference.com has a system for determining a player’s share of the MVP vote, which is a more precise metric than a binary first-second-third and even allows us to distinguish among near-unanimous awards from more contested votes.

For example, Bill Walton had 0.117 MVP vote shares in 1977 (when he finished second) and 0.403 MVP vote shares in 1978 (when he won). He goes in the books with 0.52 career vote shares. The all-time leader here through 2022–23 is LeBron James, with 8.8.

One note here: There are eight players (Julius Erving, Rick Barry, Billy Cunningham, Spencer Haywood, Artis Gilmore, Connie Hawkins, George McGinnis, and Mel Daniels) who factor at least somewhat into the top-100 discussion and received significant ABA MVP vote shares; I took these at one-third of their value. This feels like a fair adjustment: first, because the ABA had half as many teams as the NBA for nearly the entirety of its existence and, second, while it was close to the NBA in quality, I don’t think anyone thought it achieved full parity.

Additionally, I had to go back in time and give an estimated 3.5 MVP vote shares to George Mikan; the league didn’t give out the award until 1955–56, when Mikan’s prime years had passed. If you’re scoring at home, I also gave 1.0 to Joe Fulks and 0.5 to Paul Arizin.

• First Team All-NBA: 10 points each
• Second Team All-NBA: 3 points each
• Third Team All-NBA: 1 point each
• First Team All-ABA: 5 points each

Roughly tripling the value between First and Second Team, and again between second and third, keeps the emphasis on the highest-order achievements. Note that even First Team All-NBA is just one-fifth as valuable as a full MVP vote share. Consistent with the treatment above, I also halved the reward for achieving ABA First Team and didn’t acknowledge the second team.

Finals MVP: 10 points

Note that for those who played before the advent of the award in 1969, I had to “award” a Finals MVP based on who likely would have won it that year. I handed out seven to Bill Russell, four to George Mikan, one more to Wilt Chamberlain, and one each to Bob Pettit, Bob Cousy, Paul Arizin, Bob Davies, Sam Jones, and Dolph Schayes. Hopefully you agree with my voting.

All-Star team: 1 point

In the context of comparing all-time greats, making the All-Star team is just not that big a deal; it’s the floor, not the ceiling.

Every player in the GOAT points top 100 was named to at least five All-Star teams except the players from before the ’50s, who didn’t have an All-Star Game to play in. (I “selected” those players for the years they were first-team all-league and didn’t have a game to play in.)

I did not acknowledge making an ABA All-Star team; in conferences with five and six teams, respectively, the bar was just too low.

Career win shares above 100: 1 point

To balance some of the emphasis on peak value versus career value, and to reward more general team accomplishment and durability, I added a bonus for players who achieved at least 100 career win shares on basketball-reference.com. This is a fairly simplistic measurement, yes, but it has the advantage of being available back to the beginning of the NBA.

Conveniently, 96 players in NBA history had at least 100 career win shares through 2022–23, and received extra points this way. Most got scraps, however; only 24 players in league annals have cleared 150 win shares. Setting a bar at 100 strikes a balance between rewarding quality longevity without overly rewarding “hanging around” years or overly punishing players with brief peaks.

Note that I did not count ABA win shares here; there are some totals from the early years of that league especially that are just batty; suffice to say it produced results that I do not think I could defend.

Career BPM above 2.0: 7.5 points per point

Finally, we have a contribution from the advanced stats, somewhat. Basketball-reference.com only has BPM dating to 1974, and uses some tricks to fill in gaps for everything prior to 1985, so it’s definitely more valuable for modern players than for old-timers. I included it here to help weigh the modern players in particular; I think it’s hard for us to answer the question “How great is Paul George?” while his career is going on, and this helps provide a historical guidepost.

The limitation here is that I had to make crude estimates for pre-1974 players, generally giving them the benefit of the doubt and rating them comparable to historical peers from later eras. Because of this, I had to make BPM’s contribution relatively minor; doubling my estimate for Elgin Baylor, for instance, would only move him up three spots in the GOAT point standings.

So what do GOAT points give us? Still a lot of questions about comparing eras and roles, of course. What do we do with Mikan, for example? GOAT points tells us something we already know — he dominated the early 1950s — but tells us nothing about the relative strength of the league then versus in 1972, let alone 1992 or 2022.

For that matter, GOAT points doesn’t really know what to do with Dennis Rodman, either, or how to handle cases of extreme longevity (Karl Malone, John Stockton), or what to do about Michael Jordan skipping two years of his prime and then retiring at 35.* It can’t tell you whether Walt Frazier was better than Isiah Thomas, or if Clyde Drexler was better than Dwyane Wade, or if 1.75 God-level seasons from Bill Walton is better than 15 years of Robert Parish being the third-best center in the East.
* (Those Wizards years didn’t happen.)

What it can do, at least, is set the stage for the discussion. Maybe I weighted some stuff too highly and other things not highly enough; surely there are ways this can be improved in the coming years, especially if we get better historical advanced stats.

That said, it also brings some important debate questions to light, particularly regarding a few players who were excluded from this list or, perhaps, vaulted too prominently in it.

OK, enough of my yapping. It’s time for the envelopes. Here’s what the GOAT points formula spits out for the top 100 players in pro basketball history:
