Has an Olympic Basketball (Men) game ever ended 109-101?
Exactly once. On July 24, 1996, Australia beat Brazil 109-101, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 109-101 in league history.
That makes 109-101 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 110-101 has happened never and 109-102 has happened never.
