Because I need something to think about, Group B plays out this way - assuming both Russia and the Czechs both beat Austria.
**
If Russia and the U.S. both beat Sweden...
Russia
U.S.
Sweden
Czechs
**
If Sweden beats both the U.S. and Russia...
Sweden
Russia
U.S.
Czechs
In this case, Sweden finishes first with 12 points.
Russia, the U.S. and the Czechs finish with 6.
The Czechs have the worst goal differential of the 3 so they finish 4th.
Russia beat the U.S. so the U.S. gets 3rd place.
**
If Sweden beats the U.S. but loses to Russia...
Russia
Sweden
U.S.
Czechs
**
If Sweden loses to the U.S. but beats Russia...
U.S.
Sweden
Russia
Czechs
**
Feel free to correct me if I am wrong.
O.T. in either of the Sweden games and everything changes.
