The Blueprint: The Genesis of the Three-Point Line

In the summer of 1967, as the National Basketball Association (NBA) enjoyed its status as the sole major professional basketball league in the United States, a rival consortium of investors and team owners launched the American Basketball Association (ABA). From its inception, the ABA faced an existential challenge: how to capture audience attention in a crowded sports market dominated by the established NBA. The solution, radical for its time, was to reimagine the very geometry of the game. Among its most famous innovations—the red-white-and-blue ball, the slam dunk contest, and the three-point line—the latter would ultimately prove to be the most transformative, though not in the ways its creators initially envisioned. This chapter traces the genesis of the three-point line from its conception as a marketing gimmick in the ABA to its tentative adoption by the NBA in 1979, examining the gap between its stated intentions and its clumsy early implementation. We will profile the first pioneers who dared to shoot from beyond the arc and analyze why, despite its potential, the three-point line remained an underutilized strategic variable for over a decade—a sleeping giant waiting to be awakened.

The ABA’s Gamble: Innovation out of Necessity

The late 1960s were a period of stagnation for professional basketball in America. The NBA, while stable, played a brand of basketball characterized by deliberate pacing, dominant centers, and low-scoring affairs. Games often resembled tactical battles in the paint, with field goal percentages hovering around 43% and scoring averages well below modern levels. Against this backdrop, the ABA’s founders—a group including former NBA star George Mikan, who served as the league’s first commissioner—embraced a philosophy of "showtime" basketball. Their objective was not merely to compete but to differentiate, to create a product that was faster, more spectacular, and more accessible to a television audience. The three-point line emerged from this strategic imperative as a deliberate engineering of excitement.

The concept of rewarding long-distance shooting was not entirely novel; barnstorming teams and amateur leagues had experimented with similar ideas. However, the ABA formalized it with specific parameters: a 25-foot (7.62-meter) arc from the basket, with the exception of the corners, which were also 25 feet at the time (unlike the NBA’s later shorter corner distance). The stated goals were twofold. First, increase scoring by incentivizing shots from greater distances, thereby creating more possessions and higher point totals. Second, "open the floor" by pulling defenders away from the basket, theoretically creating driving lanes for slashers like Julius Erving and facilitating a more fluid, entertaining style of play. In the words of one ABA executive, "We wanted to make every shot a potential three-pointer, to keep fans on their feet."

Yet, the implementation was clumsy from the start. Players, many of whom had honed their skills in college basketball where no such line existed, struggled to gauge the new distance. Early ABA games featured heaves from well beyond the arc, often with little regard for shot selection, as the novelty encouraged volume over efficiency. The league’s first season in 1967-68 saw teams average 6.3 three-point attempts per game, but with a collective field goal percentage of just 26.4% from deep—a figure that would be considered abysmal even by today’s standards. The gimmick, while successful in generating buzz, did not immediately translate into a sustainable tactical advantage. Instead, it became a sideshow, a marketing tool that differentiated the ABA’s product but did not yet redefine its core strategy. The line was drawn, but its strategic potential remained dormant, buried beneath a layer of skepticism and misapplication.

The NBA’s Cautious Adoption: Merging Leagues, Merging Rules

The ABA’s experiment with the three-point line lasted nine seasons before financial pressures led to a partial merger with the NBA in 1976. Four ABA teams—the Denver Nuggets, Indiana Pacers, New York Nets (now Brooklyn Nets), and San Antonio Spurs—were absorbed into the established league. However, the NBA’s leadership, steeped in tradition and wary of altering a product they believed was already superior, did not immediately adopt the ABA’s rulebook wholesale. While the merger brought the three-point line into the NBA’s orbit, its implementation was delayed for three more years, a period marked by internal debate and cautious experimentation.

The NBA’s reluctance stemmed from multiple sources. Purists within the league office, coaching ranks, and media viewed the three-point shot as an artificial contrivance that threatened the fundamental balance of basketball. Traditionalists argued that the game should be decided by fundamental skills—post moves, mid-range jumpers, and team defense—not by "circus shots" from the periphery. Critics, including legendary Boston Celtics coach Red Auerbach, publicly dismissed the three-pointer as a gimmick that would cheapen the sport. "Basketball is a game played inside," Auerbach famously contended. "This long-distance stuff is for show, not for winning." Such sentiments reflected a broader cultural resistance to change; the NBA had just emerged from a period of growth and was reluctant to tamper with a formula that seemed to work.

Behind the scenes, however, pragmatic considerations eventually prevailed. The NBA’s new commissioner, Larry O’Brien, recognized that the merger required a unification of rules to maintain competitive equity. Moreover, the league faced declining scoring in the late 1970s, with the 1978-79 season seeing an average of just 107.0 points per game—the lowest since the 1954-55 season. Television executives and fans alike craved more action and higher scores. The three-point line, despite its flaws, offered a potential antidote. After extensive testing in exhibition games and the NBA’s summer league, the league officially announced that the 1979-80 season would feature the three-point line at a distance of 22 feet (6.7 meters) from the basket—shorter than the ABA’s 25 feet, a nod to the NBA’s preference for a more "reasonable" arc that would encourage, but not overwhelm, the shot.

The adoption was thus a compromise: a nod to innovation tempered by conservatism. The NBA did not embrace the three-pointer as a revolutionary weapon but as a subtle tweak, a variable to be monitored. The rulebook specified that a player’s feet must be completely behind the line at the moment of release, and that the shot would count for three points only if the shooter did not foul. These technical details, while seemingly minor, would later become focal points of strategic debate. For now, however, the NBA’s message was clear: the three-point line was here, but it was not to be trusted.

October 12, 1979: The First Shots

The night of October 12, 1979, marked the symbolic dawn of the three-point era in the NBA. Across two venues, history was made almost simultaneously, though only one moment would be immortalized as the first. In Boston, the Celtics hosted the Houston Rockets at the Boston Garden. With 9:42 remaining in the first quarter, Celtics guard Chris Ford caught a pass from Larry Bird near the right wing, elevated, and released a clean jumper from 23 feet. The ball swished through the net, eliciting a mixture of surprise and tentative applause from the crowd. Ford’s basket was officially recorded as the first three-point field goal in NBA history.

Meanwhile, in Detroit, the Pistons faced the Milwaukee Bucks at the Silverdome. Late in the first quarter, Pistons rookie Mike Brkovich, a 6-foot-5 shooting guard from Canada, received a pass on the left baseline and sank a three-pointer of his own. Brkovich’s shot occurred approximately two minutes after Ford’s, but its significance would resonate differently. While Ford’s goal was a footnote in a Celtics v
