Instant Replay for Buzzer-Beaters
The Rule Change
The NBA expanded instant replay to allow officials to review whether a shot was released before the buzzer at the end of any quarter. Previously, officials had to make these split-second determinations in real time with no mechanism for correction.
Statistical Impact
Improved accuracy on some of the most dramatic and consequential moments in basketball. Buzzer-beater reviews became routine, ensuring that game-winning shots were legitimately scored within the time limit. This was an early step in the broader expansion of replay that would accelerate through the 2010s.
