April 22, 1954 – The NBA introduced the 24-second shot clock to speed up the game. The number was devised when Syracuse Nationals owner Danny Biasone divided the seconds in a 48-minute game by the the average amount of shots by both teams (120) from games played from the previous three seasons. The game was dull and played at a snail’s pace, with one team opening up a lead and freezing the ball until time ran out. The only thing the trailing team could do was foul. Thus the games became rough, ragged and free-throw shooting contests.
“The adoption of the clock was the most important event in the NBA,” NBA President Maurice Podoloff said.
Legendary Celtics coach Red Auerbach called it the single most important rule change in the last 50 years.
