Partially correct, but it wasn't a true round robin. It was an odd format, at least odd to me. There was group play, then a medal round. Two groups. Top two teams from each group advanced to the medal round. The medal round wasn't a full round robin among the four remaining teams. In the medal round, the teams only played teams from the other group and did not play a second game against the team in their group that had also advanced to the medal round. Instead, the group results between the two medal round teams from the same group were counted for medal round purposes.
It is a common misconception that the US won the gold when they beat the Russians. As it played out, the US had to beat the Finns to get the gold. In what would have been the most unfair of results, if the US had lost to the Finns, Tucker's team would have won the gold. I think Finland would have won silver and the US bronze, but I'm not positive about that.
Pretty strange way to run a railroad if you ask me (they didn't). Why not have the first place team from group A play the second place team from group B and B-1 play A-2 in the semis, then the winners play in the finals?
