Has an Olympic Hockey (Men) game ever ended 16-2?
Exactly once. On February 9, 1984, Finland beat Norway 16-2, and no Olympic Hockey (Men) game before or since has ended that way. When it happened it was a scorigami, the first 16-2 in league history.
That makes 16-2 the 75th most common final score out of 99 that have ever occurred in Olympic Hockey (Men). One point away, 17-2 has happened 1 times and 16-3 has happened 1 times.
