Has an Olympic Basketball (Men) game ever ended 86-38?
Exactly once. On January 1, 1968, Mexico beat Morocco 86-38, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 86-38 in league history.
That makes 86-38 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 87-38 has happened never and 86-39 has happened never.
