* Prior to 1980, USSR pros had lost in hockey to USA amateurs, in 1960.
* Americans were on home ice.
* Soviets were having an underwhelming tourney.
* Soviets were extremely overconfident vs USA.
* Moreover, not a single game was ever in doubt.
* Soviets changed their head coach, for political reasons, immediately before the tourney.
* Soviets barely survived the semifinal against Cuba...
And the ending!
Still the US was an enormous favorite
