1.2: The Founding League, 1946 to 1954

Chapter 1: History and eras

The BAA, the merger that produced the NBA, Mikan and the early Lakers, and the stalling that produced the shot clock.

No new terms introduced. No diagrams.

Eight years separate the first professional season that lasted from the rule that made the professional game watchable. This is the shortest era in the chapter and the one with the clearest ending: the sport acquired a single league, discovered that a league can be won by not playing, and fixed it with a clock.

Era
The founding league, 1946 to 1954
Begins
November 1946: the Basketball Association of America plays its first season.
Ends
1954: the 24-second shot clock is adopted for the 1954-55 season.
What it looked like
One league where there had been several, a dominant big man, and a game a leading team could stop playing.
Era 1: The founding league: a single league, and then a reason to shoot.

1 One league

The BAA began in 1946-47 and was not alone: the National Basketball League already existed. The two merged, and NBA.com’s account of the 1949-50 season states the terms: “the summer of 1949 solidified the professional basketball picture, with the six surviving NBL teams being absorbed into the BAA and the league being renamed the National Basketball Association.”1

That single sentence contains the whole of what this era did structurally. The name the league has used ever since dates from that summer, and the season that followed was the first played under it.

2 Mikan

The era’s defining player was George Mikan, whose Minneapolis Lakers won the first NBA season: NBA.com’s review of 1949-50 records the season “in which the Minneapolis Lakers emerged as NBA champions” and that “George Mikan led the league” that year.2 He was inducted into the Hall of Fame in its inaugural class, which the Hall’s own list records as “Class of 1959”,3 and Wikipedia’s account of that class adds that he “was the first NBA player to be enshrined.”4

Why he mattered
The first player the league wrote rules about rather than for, and the reason the lane was widened while he was still playing.
Player 1: George Mikan: the first player whose presence changed the rules written around him.

The post-up of lecture 3.7 is the action this era was built on, and Mikan is the reason. An offense whose best player stands near the rim with his back to it is an offense that does not need spacing, a three-point line or a ball screen, and for most of this era it did not have any of them.

3 Bob Cousy and the first fast break

The other player this lecture cards is the one who made the ball move. Bob Cousy won the Most Valuable Player award once, in 1956-57, which is the single row naming him on the league’s year-by-year list,8 and he entered the Hall of Fame in the Class of 1971.9

Second bearing

Why he mattered
The first guard whose passing was the reason a team ran, and the player the early transition game was built around.
Player 2: Bob Cousy: the ball moving ahead of the defense, twenty years before anyone counted what that was worth.

His award falls just after this era’s boundary, which is worth stating rather than smoothing over: the MVP award did not exist during most of the founding league, and a player whose best years were before an award cannot be measured by it. That is the reason this chapter counts honors rather than compares them across eras.

4 The clock

The era ends with an arithmetic problem. Nothing in the rules obliged a team with a lead to shoot, so the rational thing to do with a lead was to hold the ball, and teams did. NBA.com’s review of the 1954-55 season records the fix: “it was the adoption of the 24-second clock and an accompanying limit on the number of fouls a team could commit in a quarter.”12 The same page names its author, “Syracuse owner Danny Biasone and his GM, Leo Ferris, came up with the shot clock idea”,13 and quotes the former coach and referee Charlie Eckman: “Danny Biasone saved the NBA with the 24-second rule, make no mistake about that”.14

The clock is the most consequential rule in this chapter, because it created the thing every later lecture assumes: a possession with an end. Pace becomes a number only once possessions are countable, late clock becomes a situation only once there is a clock to be late on, and transition becomes worth measuring only once the alternative has a deadline.

The idea to carry into lecture 1.3 is that the clock did not make the game fast. It made it finite, and the twenty-five years that follow are the sport working out what to do with a possession that has to end.
