The Origin Story: A Line, a Distance, a Revolution

The Origin Story: A Line, a Distance, a Revolution

A 23-foot, 9-inch arc. That is the only physical difference between professional basketball of 1979 and professional basketball of today. The rules of the game, the dimensions of the court, the height of the rim, the circumference of the ball, the size of the backboard, the number of players, the length of the quarters - none of it changed. And yet, in the four decades between those two eras, the three-point line went from being an exotic novelty that coaches tolerated to the gravitational center of elite offense. A fan who watched Game 1 of the 1985 NBA Finals and then watched Game 1 of the 2015 NBA Finals would have been forgiven for believing they had stumbled into two different sports. The Boston Celtics and the Los Angeles Lakers combined for 5 three-point attempts in that 1985 game. The Golden State Warriors and the Cleveland Cavaliers combined for 48 in the 2015 game. Same basket. Same ball. Same ten bodies on a 94-foot floor. The only meaningful variable was how often those bodies stood behind the arc and shot.

So what happened, exactly? Why did the NBA adopt a rule in 1979 that the league did not truly exploit until the 2010s? Why did generations of coaches - some of the sharpest basketball minds of the twentieth century - look at a shot worth 50 percent more than another shot and conclude, calmly and often vocally, that shooting it was a *bad idea*? Why did it take three decades for the math to win? And, more importantly, what does that thirty-year gap tell us about how every other "revolution" in basketball - and in any other human system - actually unfolds?

This chapter opens the book by treating the three-point line as a case study in slow revolutions. The line itself was the easy part. Somebody could paint it on a gymnasium floor in an afternoon. What took thirty years was everything *around* the line: the shooting technique, the offensive schemes, the defensive rotations, the coaching vocabulary, the front-office analytics, the player-development pipeline, the broadcast conventions, and the cultural permission to take the shot in the first place. The line was a piece of geometry. The revolution was a piece of architecture. And architecture - unlike geometry - takes time, materials, and people who agree on what to build.

The Invention Nobody Wanted: From Peach Baskets to the Painted Arc

Basketball was invented in December 1891 by a Canadian physical-education instructor named James Naismith, who was given fourteen days by his boss at the YMCA Training School in Springfield, Massachusetts, to come up with an "athletic distraction" for a rowdy winter class. Naismith nailed two peach baskets to the railing of the gymnasium balcony, ten feet off the floor, and wrote thirteen rules. None of those rules mentioned a three-point line. In fact, none of them mentioned points at all - Naismith's original scoring used the words *goal* and *field goal* but no numeric values, because the very concept of distinguishing long shots from short ones simply did not occur to him. The court was small - roughly half the size of a modern NBA floor - and the only goal was to put the ball in the basket. Distance was an inconvenience, not a variable.

The game spread from Springfield to YMCAs across North America within a year, and as the court expanded and the players grew taller and the tactics matured, the question of "how far is too far" became increasingly practical. By the 1930s, organized leagues had begun experimenting with designated shooting zones. The American Basketball League, a short-lived professional circuit that ran from 1925 to 1955, used a "long goal" of twenty-five feet on some courts. The Harlem Globetrotters, who never joined a real league, popularized a trick-shot three-pointer in exhibitions. But none of these experiments stuck. They were curiosities - cool in a gym class, distracting in a playoff game.

The first serious scholarly proposal for a three-point line came in 1945 from Howard Hobson, the head coach at Columbia University. Hobson published an article in *The Basketball Guide* arguing that the long-range shot should be worth more points because it required more skill, more courage, and more spacing on the floor. He proposed an arc at twenty-one feet. The idea was reviewed by the rules committee and quietly shelved. The basketball establishment of the 1940s, which was dominated by former players and coaches who had built their reputations on the post-up, the mid-range jumper, and the fast-break layup, saw no reason to reward a shot they considered a heave. For another fifteen years, that's where the idea stayed: in the heads of a few coaches, on the pages of a few coaching manuals, never quite reaching a real game.

The first league to actually use the three-point line in a real game was the American Basketball League - not the 1920s version, but a new, short-lived rival league founded in 1961. The ABL, which tried to challenge the NBA with a faster pace and a higher-scoring style, adopted a three-point arc at twenty-five feet for the 1961-62 season. Vince Boryla, a former NBA player who had won a championship with the Minneapolis Lakers in 1949 and later coached the U.S. Olympic team, served as the league's commissioner and pushed the rule through. Boryla believed the long shot would open the floor and reward skilled shooters, and he wanted the ABL's product to look visibly different from the NBA's half-court, two-point grind. The rule worked - sort of. Players loved the three. Coaches were skeptical. And the ABL folded after just half a season, taking its arc with it.

The American Basketball Association, the upstart league that began play in 1967, saw what the ABL had done and copied it. The ABA, founded by Dennis Murphy and Gary Davidson, wanted to differentiate itself from the NBA at every turn: a red-white-and-blue ball, a faster shot clock, slam-dunk contests at the All-Star break, and, most consequentially, a three-point line. The ABA's arc was set at twenty-five feet for most of its existence and adjusted in 1979 to a uniform twenty-two feet around the perimeter, slightly shorter than the modern NBA distance but in the same spirit. The ABA's first three-pointer in league history was hit by Roger Brown of the Indiana Pacers in 1967. Brown's shot was barely noticed by national press. The league had no national TV contract, and most sportswriters still treated the ABA as a curiosity. But the shot did two things that mattered: it proved the rule could be played under real-game conditions, and it gave the NBA a competitor whose existence could be used as an argument for change.

The NBA resisted for over a decade. The arguments against the three-point line, as recorded in league memos and coaching-clinic speeches from the 1960s and 1970s, were almost identical to the arguments that would later be deployed against it from the bench. First, the math: a player who shoots 50 percent from two-point range scores 1.0 point per attempt, and a player who shoots 33 percent from three-point range also scores 1.0 point per attempt, so the two shots are mathematically equivalent if the percentages hold. The implicit assumption - that hitting a longer shot is *harder*, and therefore the percentages will always favor the shorter shot - seemed obvious to coaches who had spent their careers teaching form shooting from fifteen feet. Second, the style: the NBA's most popular teams in the 1970s, like the Knicks and the Lakers, played a low-pace, post-oriented game that prized mid-range artistry. The three-pointer was seen as a *desperation* shot - something you threw up at the buzzer when nothing else had worked. Building your offense around it was, in the language of the time, "foolish." Third, the optics: NBA executives worried that three-point attempts would lower television ratings. Stars like Julius Erving, whose highlight dunks drove viewership, would be replaced by three-point
