Has an Olympic Basketball (Men) game ever ended 77-68?
Exactly once. On September 2, 1960, Brazil beat Poland 77-68, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 77-68 in league history.
That makes 77-68 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 78-68 has happened 1 times and 77-69 has happened never.
