Has an Olympic Basketball (Men) game ever ended 115-75?
Exactly once. On August 1, 1996, Greece beat China 115-75, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 115-75 in league history.
That makes 115-75 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 116-75 has happened never and 115-76 has happened never.
