Daryl Morey

Morey began his career in 1992 with STATS, Inc., a pioneer sports data firm where Bill James also worked. During his time there he was the first to adapt James' Pythagorean expectation to professional basketball. He found that using 13.91 for the exponents provided an acceptable model for predicting won-lost percentages:

${\displaystyle \mathrm {Win} ={\frac {{\text{points for}}^{13.91}}{{\text{points for}}^{13.91}+{\text{points against}}^{13.91}}}.}$

Morey's "Modified Pythagorean Theorem" was first published in STATS Basketball Scoreboard, 1993–94.[6]

In 2000, Morey worked at EY-Parthenon, a leading strategy consulting firm, as a principal consultant with an emphasis on sports.

Morey is the co-chairperson for the annual MIT Sloan Sports Analytics Conference. He is also an avid Esports supporter, has attended MLG (Major League Gaming) events, and was part owner of Clutch Gaming, the Houston, Texas-based League of Legends Championship Series eSports team. Morey is also passionate about musical theater. He commissioned and produced the basketball themed musical Small Ball,[7] which opened in April 2018 at the Catastrophic Theater in Houston, Texas.[8]

In 2002 Morey left EY-Parthenon to become senior vice president of operations for the Boston Celtics, with responsibility for setting ticket prices and developing analytical methods and technology to enhance basketball decisions related to the draft, trades, free agency, and advance scouting of opponents for the coaching staff.[9]

Then-Houston Rockets owner Leslie Alexander named Morey the team's assistant general manager on April 3, 2006. Morey succeeded Carroll Dawson as general manager on May 10, 2007, following the Moreyball trend of integrating advanced statistical analysis with traditional qualitative scouting and basic statistics.[10] Although several teams had previously hired executives with non-traditional basketball backgrounds, the Rockets were the first NBA team to hire such a general manager. In the fall of 2012, he and the Rockets acquired now-All-Star and 2017-18 league MVP James Harden via trade from the Oklahoma City Thunder. During Morey's tenure, the Rockets did not have a losing record and advanced to the playoffs 9 times, including to the Western Conference Finals in 2015 and 2018. He was also named the NBA Executive of the Year in 2018.

On October 15, 2020, the Rockets announced that Morey would step down as general manager on November 1, 2020.[11] He confirmed his departure in a full-page ad in the Houston Chronicle on October 18, 2020.[12] After Morey's departure, the Rockets would embark on a rebuild by trading away Russell Westbrook and James Harden.[13][14] Morey's resignation made Donnie Nelson of the Dallas Mavericks the longest-tenured general manager in the NBA, as Presti was hired in June 2007, a month after Morey became the Rockets' GM.

On November 2, 2020, the Philadelphia 76ers named Morey as president of basketball operations.[15]

On March 22, 2021, Morey said "3-pointers should be worth 2.5 points" and the court should be widened to make corner 3-pointers longer.[16]

Author of Moneyball, Michael Lewis, chose Daryl Morey as the new nerd-hero at the center of his 2016 book, The Undoing Project. Whereas Moneyball highlighted the plight and success of Billy Beane as GM of the Oakland Athletics in 2003, The Undoing Project reveals Daryl Morey as the underdog king of basketball, making use of a similar analytical method to acquire undervalued talent as Beane did with the A's to produce a forceful team. Lewis uses Morey as a real-world example of one who has exemplified ideas introduced by Daniel Kahneman and Amos Tversky, two Israeli psychologists whose work pioneered the field of behavioral economics.[17][18] The psychologist duo defined a simple, two-part distinction of the way the brain makes decisions: System 1 and System 2. A more intuitive, subjective, fast, and efficient process, System 1 represents the brain's capacity to make split-second choices, often using personal experience to guide decision-making. System 2, however, characterizes a slower, more analytical process of reasoning to reach a conclusion. Michael Lewis points out in The Undoing Project how Daryl Morey observed basketball experts of the time making awfully subjective assessments in looking at basketball players. Shifting the Rockets' scouting strategy to look at hard data over simple observations, Morey implemented a more System-2-based approach to the team's hiring practices. This strategy is thought to be critically linked to the Houston Rockets' recent success.[18]

On October 4, 2019, Morey tweeted in support of the 2019–2020 Hong Kong protests, drawing criticism from Rockets owner Tilman Fertitta, who said that while Morey was the best general manager in the NBA, the Rockets were not a political organization.[19][20][21] The tweet was Morey's first public expression of political views.[22]^: 178 Morey later deleted the tweet.[20][21][23] In mainland China, where the Rockets have an extensive relationship after the selection of Yao Ming in 2002,[24][19] Morey's tweet resulted in the Chinese Basketball Association's suspension of its relationship with the Rockets and the issuance of a statement of dissatisfaction from the consular office of the People's Republic of China (PRC) in Houston.[24][25][20] All Houston Rockets-related items were removed from the Tmall and JD.com sites and the team's games were removed from broadcasting on Tencent.[26] The Associated Press said that the reactions underscored Beijing's sensitivity about foreign attitudes toward the protests.[24]

At the time of the tweet, Morey and the Rockets were in Tokyo for the NBA's Japan Games. He remained isolated in his room at the hotel and only engaged with Toronto Raptors president Masai Ujiri upon the fallout. According to Ujiri, Morey said that the timing of his tweet was in response to a new law in Hong Kong prohibiting protesters from wearing masks and that himself and his friends had discussed political autonomy in Hong Kong since attending MIT Sloan.[27]

A few days later, Morey and the NBA each issued a separate statement addressing the original tweet, with Morey saying that he never intended his tweet to cause any offense and the NBA saying that it was regrettable.[24] The statements were criticized by US politicians and third-party observers for the perceived exercise of economic statecraft by the PRC and insufficiency of the NBA's defense of Morey's tweet.[28] A bipartisan letter by Alexandria Ocasio-Cortez, Ted Cruz, and six other lawmakers fiercely criticized the NBA's handling of the controversy. The lawmakers wrote that the NBA's response not only "sold out an American citizen" but also "reinforces the Chinese Communist Party view that those who point to Chinese repression in Hong Kong are at best stating opinions, not facts", as well as being "a betrayal of fundamental American values".[29][30][31] Critics also contrasted the league's disparate response to Morey's tweet with its history of political activism[32] and compared the incident to an October 2 South Park episode "Band in China" which parodies the self-censorship of the American entertainment industry to meet PRC censorship demands.[33] The statements also drew criticism from PRC state-run media for their perceived insufficiency, as Morey himself did not apologize.[34][35]

NBA commissioner Adam Silver later defended the league's response to the tweet, supporting Morey's right to freedom of expression while also accepting the right of reply from the government of and businesses from mainland China.[36] Further fallout from the tweet included the decision by China Central Television to cancel the broadcasting of two NBA preseason games,[37] pro-Hong Kong protest demonstrations held at preseason games in the United States involving teams from the Chinese Basketball Association,[38][39] the cancellation of NBA Cares community events in Shanghai,[40][2] criticism by then-president Donald Trump of the perceived double standards by the reactions of specific coaches to NBA response relative to their past criticisms of his policies,[41] and the suspension/termination of all mainland Chinese sponsors of the NBA.[2][3] A Fox Business article said that the NBA would look to Africa and India for growth if the league were to sever ties with mainland China as a result of the tweet.[42]
