How the Three-Point Line Quietly Rewired Every NBA Roster

For the first fifteen seasons of its existence, the three-point line was treated by most NBA coaches as a gimmick. In the 1979-80 season, the league's first with the shot, teams averaged just 2.8 three-point attempts a game across an entire roster, according to Basketball-Reference's year-by-year attempt totals. A player who spent practice time on that shot was usually seen as a specialist, not a building block. That view has reversed almost completely. By the 2021-22 season, NBA teams were putting up 35.8 three-pointers a night, more than twelve times the rate from four decades earlier.

The shift did not arrive at a steady pace. It came in bursts tied to specific coaches, front offices, and a change in how teams measured value on the floor. Reading the attempt data year by year explains why shooting range, not height or scoring average, is now the trait rosters get built around.

The Slow Build Before the Explosion

Growth in three-point volume was gradual through the 1990s and early 2000s, then accelerated. Mike D'Antoni's Phoenix Suns pushed the pace in the mid-2000s, leading the league with 24.7 three-point attempts a game in 2004-05, 25.6 in 2005-06, and 24.0 in 2006-07, numbers that looked extreme at the time but read as ordinary within a decade. League-wide attempts climbed from 15.8 per game in 2004 to 18.1 by 2008. By 2014-15, the Golden State Warriors, already stacked with shooters, averaged 27.0 attempts a game, and that figure ranked only fifth in the league, a sign the whole sport was catching up at once. League average hit 32.0 attempts a game by 2018-19.

Moreyball Arrives in Houston

No single front office pushed the math harder than the Houston Rockets under general manager Daryl Morey, who ran the team from 2007 to 2020. Morey's staff concluded that dunks, layups, free throws, and three-pointers were the only shots worth taking in volume, and that the long two-point jumper, the shot most players had been trained on since childhood, was the least efficient look in basketball. The approach became known around the league as Moreyball, a nod to Michael Lewis's Moneyball and its application of statistical analysis to a sport that had long trusted instinct over data.

The clearest proof came in 2017-18, when the Rockets took 81.8 percent of their shots from either the restricted area or beyond the arc, the highest share any team had ever posted, and became the first team in NBA history to attempt more than half its shots from three-point range in a season. Over Morey's thirteen years running the front office, Houston posted the second-most wins in the league, trailing only the San Antonio Spurs, while running an offense that had almost entirely eliminated the midrange jumper from its playbook.

What the Shift Did to Rosters

Once shot selection changed, personnel decisions had to follow. Centers who could only score with their back to the basket became harder to play alongside modern spacing, while forwards and even some centers who could shoot from distance became more valuable regardless of their rebounding or defensive numbers. Teams stopped drafting and signing players purely for size, and started asking whether a big man's game could survive next to four shooters spread around the arc. That question did not exist in a serious way before the mid-2010s. It is now one of the first things a front office evaluates in a draft prospect or trade target, alongside the more traditional questions about athleticism and defense.

The Center Position Reinvents Itself

No single player illustrates the personnel shift better than Brook Lopez. Across his first eight NBA seasons, all spent as a back-to-the-basket scorer for the Nets, Lopez attempted a combined 31 three-pointers. In 2016-17, under new Brooklyn coach Kenny Atkinson, he attempted 387, making 134 of them at a 34.6 percent clip. The jump amounted to the largest single-season increase in three-point attempts per game in NBA history, and it did not end his career, it extended it. Lopez went on to anchor Milwaukee's 2021 championship defense while spacing the floor from the perimeter, a role that would have been unthinkable for a center of his size a decade earlier.

Sports analyst Kirk Goldsberry, whose 2019 book Sprawlball used shot-location data to map the change, documented how the midrange area of the floor, once the bread-and-butter zone for post scorers and pull-up shooters alike, had been squeezed to near irrelevance for the league's best offenses. His shot charts showed the floor splitting into two profitable zones, the restricted area and above the three-point line, with the space in between going largely empty on the highest-efficiency teams. Lopez's transformation was an individual player adapting to exactly the trend Goldsberry's maps were describing at a league level.

What Teams Pay For Now

The dollar figures show how far the preference has traveled. Analysts covering NBA contracts have pointed to Aaron Nesmith's three-year, thirty-three-million-dollar deal with the Indiana Pacers as a reference point for what a reliable three-and-D wing costs in a league starved for that skill set, with some estimates putting a truly elite version of that profile closer to twenty-five million dollars a season. Wings who shoot and defend are treated as the scarcest resource in the sport, more prized in negotiations than raw scorers who cannot guard their position or space the floor. Teams that once paid for size now pay for range, and the shift shows up in every free agency period.

The Practical Lesson for Roster Builders

The attempt-rate data tells a simple story: efficiency arguments that once sounded like spreadsheet trivia became the operating principle of an entire league within a decade. Front offices that adapted early, Houston most aggressively, built rosters that outperformed their raw talent level for years. The lesson has outlasted the specific teams that proved it. A player's shooting range now shapes his role, his contract, and his trade value before his height or vertical leap ever enters the conversation.
