Has an Olympic Basketball (Men) game ever ended 52-43?
Exactly once. On July 27, 1952, France beat Chile 52-43, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 52-43 in league history.
That makes 52-43 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 53-43 has happened never and 52-44 has happened 1 times.
