Finland
Canada
Czechia
Germany with the upset
That would be my ideal results. I think it will not go like this (I think SWE, USA and CH, with GER - CH being a toss-up). But it is exactly how I want it to go.
Not that FIN would deserve it this year - they have been quite dire to watch - but I like upsets at the knockout stages, and Sweden have been coasting, very impressive, so that would be the biggest upset in the four pairings (along with Slovakia beating Canada, but I just don’t see that happening. The specificities of the SWE / FIN long-standing rivalry may mean that FIN somehow pulls it off.
