Has an Olympic Basketball (Men) game ever ended 69-64?
Exactly once. On August 26, 2004, Argentina beat Greece 69-64, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 69-64 in league history.
That makes 69-64 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 70-64 has happened 1 times and 69-65 has happened 1 times.
