This piece covers how NBA exec Daryl Morey uses data and systems thinking. He believes superstars are so valuable in basketball that you should trade anything for them, citing Joel Embiid (top center, great shooter) and James Harden (elite passer). He criticizes soccer's rules as the worst among major sports—offside is confusing and penalties are too harsh. Morey advises people to reject default behaviors and constantly improve themselves.
Daryl Morey (President of Basketball Operations for the Philadelphia 76ers) discussed systems thinking and data analysis in sports on the program. Key insights include: superstars are critical to success in basketball, and resource concentration influences game outcomes; he optimizes player attribut
Daryl Morey (President of Basketball Operations for the Philadelphia 76ers) is one of the pioneers of the data analytics movement in the NBA, with his approach famously known as "Moreyball." In this episode, he explores the core principles of sports as a complex system: the decisive role of superstars in basketball, how resource concentration affects game outcomes, and how KPI-driven decision-making works. The most impactful takeaway from the entire episode: Morey argues that in basketball, the value of a superstar is "asymptotic"—their impact is so immense that "you can trade everything that isn't bolted to the floor to get them," making even seemingly insane trades justifiable.
Daryl Morey argues that basketball is a near-perfect sport because it sits at the golden midpoint between "data-solvable" and "art-unsolvable."
Morey contrasts basketball with baseball and football: baseball is a static event between pitcher and batter, almost entirely explainable by data; football involves 22 players moving simultaneously, making it nearly impossible to explain with data. Basketball falls in between—a single jump shot involves countless variables (player training, defensive quality, passing quality), where data can guide decisions but can never fully "solve" the game.
> "Basketball will never be solved. If you think about a jump shot—is it because the player practiced 10,000 hours beforehand? Or because the defense was too poor? Or because the pass was too good? A single jump shot has that many variables."
Key data point: Morey notes that the data signal-to-noise ratio in the NBA is far higher than on Wall Street—quantitative analysts would be "wide-eyed" upon hearing this—but the NBA requires being the best among 30 teams, while investing only needs to outperform the S&P 500 by 2%.
Morey argues that the value of superstars in basketball far exceeds that in other sports, making resource concentration a core variable in determining championship outcomes.
Morey uses baseball as a comparison: at his peak, Barry Bonds (baseball) could only bat 4-5 times per game, whereas Joel Embiid (basketball) can attack continuously; more critically, in basketball, a superstar can "choose" which defender to face through pick-and-rolls—equivalent to Bonds not only batting nine times in a row but also selecting which pitcher to face.
Key data: Certain superstars can contribute nearly 30 wins in a single season (over 82 regular-season games). Morey notes that only 8-9 teams (in a good year) in the NBA have a championship chance at the start of the season, and in most years, only 3-4.
Reader's note: As a team executive, Morey's "superstar-first" argument reflects his position-holder perspective—this is both an objective fact and a justification for the rationality of his team-building strategy.
Morey describes a carefully designed decision-making process aimed at minimizing human bias and groupthink.
The process includes a seven-person "Small Council" (akin to the Small Council in Game of Thrones), with one member participating remotely to counter groupthink; data-driven anonymous voting before meetings; and allowing the person with the "strongest feeling" to speak first during discussions. Morey emphasizes that voting methods require a trade-off between "resistance to manipulation" and "intensity of conviction" — the former using the Condorcet method, and the latter employing "draft pick equivalent" valuations.
Key Insight: Morey distinguishes between two ways of "being high" on a decision — arriving at different conclusions from the same inputs (worth discussing) versus seeing data that others have not (worth listening to). The team tracks each individual's Brier score (prediction accuracy), but acknowledges that "you might just have been lucky to be right."
Self-Reflection: Morey admits that even with these safeguards, groupthink persists — "The NBA world is like a sewing circle; everyone is talking about the same things."
Morey offers a systematic critique of soccer's rule system, arguing it is the worst among all major sports.
Core Issues:
1. Offside Rule: Incomprehensible to the average spectator, and the penalty is disconnected from whether an advantage was actually created.
2. Number of Players: 11 players per side is too many, necessitating the offside rule to prevent players from "standing at the other end waiting for the ball" — "Whoever randomly chose 11 vs. 11 got it wrong."
3. Penalty Mechanism: Either completely meaningless (a re-start) or decisive for the entire match (a penalty kick) — with no middle ground.
4. Countdown Clock: Counterintuitive.
Rebuttals to Common Defenses:
Analogy: Morey uses an NBA example to illustrate that "correlation ≠ causation" — if all top teams threw the ball out of bounds on their first possession, they would still win most games, but that does not mean "throwing the ball out of bounds" is a good strategy.
Morey argues that the core of career development is "not accepting the operating system you've been given" — that is, constantly examining and replacing your own default behavioral patterns.
Morey describes himself as naturally lacking many "basic instincts" (social skills, common sense, etc.), so from a young age he had to learn everything on his own, constantly replacing old methods with better ones. He advises young people not to cling to their "brand image" — "you've always been the person who does X" should not become a limitation.
Hiring principle: Look for people who "do what they want to do in their spare time" — Morey's best analyst in Houston was someone who wrote a blog from 2005 to 2007 and was signed to a 4-year intern contract that was "probably unconstitutional."
Observation on books: Morey points out that the incentive structure for business books is completely misaligned — authors are required to write 300 pages to enter the speaking circuit, but Kindle data shows that only a "single-digit percentage" of readers finish a book. As a result, he has turned to business book summaries and podcasts.
| Position | Guest Sentiment | Key Data |
|---|---|---|
| Joel Embiid (Philadelphia 76ers) | Bullish—one of the league's best big men | Shooting percentage near 60%, free throw percentage 88% |
| James Harden (Philadelphia 76ers) | Bullish—passing ability improves Embiid's catch positions | Specific data not disclosed |
| Yao Ming (Former Houston Rockets) | Review—historic interior player, but faced catching difficulties | "Game over" if catching within 7 feet |
| Shane Battier | Review—underrated "backcourt passer" | Trade based on assumption: unlock Yao Ming |
| Barry Bonds (Baseball) | Comparison—peak season +14 wins, but only 4-5 at-bats per game | Not disclosed |
| Stephen Curry | Comparison—his three-point ability attracts casual viewers | Not disclosed |
1. Morey: The value of basketball superstars is "asymptotic" — you can trade everything to acquire them because "you're using pennies to piece together a $100 bill." Any seemingly insane trade can be rationalized.
2. Morey: Soccer has "the worst rules among all major sports" — the offside rule is incomprehensible to the average viewer, penalties are either completely meaningless or decide the entire game, and 11 players per side is too many, requiring the offside rule as a remedy.
3. Morey: The incentive structure for business books is completely misaligned — authors are required to write 300 pages to enter the speaking circuit, but Kindle data shows that only a "single-digit percentage" of readers finish a book.
4. Morey: In decision-making, distinguish between "reaching different conclusions from the same inputs" and "seeing data that others have missed" — the former is worth discussing, the latter is worth listening to. The team tracks Brier scores but acknowledges that "you might just be lucky to be right."
5. Morey: The core of career development is "not accepting the default operating system" — constantly examine and replace your own behavioral patterns, and do not be constrained by your past "brand image."
6. Morey: Hire people who "do what they want to do in their spare time" — Houston's best analyst was someone who wrote a blog from 2005 to 2007 and was signed to a 4-year intern contract that was "possibly unconstitutional."
7. Morey: The post-negotiation phase can create win-win outcomes — after a handshake deal, both sides can more openly share their true valuations and seek better alternatives.
8. Morey: People who "don't look like" they belong in the industry are often superior — because they have to be "much better than others" to overcome the industry's "immune system" rejection.
