Has an Olympic Basketball (Men) game ever ended 74-53?
Exactly once. On August 28, 1972, Cuba beat Spain 74-53, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 74-53 in league history.
That makes 74-53 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 75-53 has happened never and 74-54 has happened never.
