What is a shot clock in basketball?
How the clock works
When a team gains possession, the shot clock starts. If the offense does not get a shot off before the clock runs out, possession goes to the other team. The clock is separate from the game clock, so both can be running at the same time.
Some plays reset the shot clock to a shorter number. In the NBA, certain offensive rebounds and other events reset the clock to 14 seconds. The exact reset rules have changed over the years, so the details matter for close calls.
- NBA shot clock is 24 seconds
- NCAA men's shot clock is 30 seconds
- Some plays reset the clock to a shorter time
- A shot clock violation gives the ball to the other team
Why it matters
The shot clock keeps the game moving and stops teams from holding the ball for long stretches. Coaches plan offensive sets around it, especially late in games when a team is trying to protect a lead or catch up.
Fans often notice the clock most in the final seconds of a possession, when a team has to shoot before the buzzer sounds. Broadcasters often show the shot clock on screen, so viewers can follow whether a team is about to run out of time.
Common mistakes
- Confusing the shot clock with the game clock, since they run separately.
- Assuming every level of basketball uses the same shot clock length.
