Has an Olympic Basketball (Men) game ever ended 70-36?
Exactly once. On January 1, 1948, Cuba beat Iran 70-36, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 70-36 in league history.
That makes 70-36 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 71-36 has happened never and 70-37 has happened never.
