Has an Olympic Basketball (Men) game ever ended 101-63?
Exactly once. On September 1, 1960, France beat Japan 101-63, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 101-63 in league history.
That makes 101-63 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 102-63 has happened never and 101-64 has happened never.
