I find Hinterland's opinions about goaltending to be pretty peculiar. Like, Pasche had a pretty successful career in the USHL for a very bad team and now has .919 Sv% in the NL at the young age of 21 and he absolutely hated the guy. It feels like he thrashes every goalie who isn't Vasilevsky-like during the WJC. It's either a bad goalie who stands on his head or a bad goalie behind a solid defensive team
He played to a 3.16 and .909 in 2017 which is decent. 1-3 record.
I think there is a big difference between bringing a good goalie and that goalie managing to have good stats behind a terrible team that Switzerland is a lot of the time at the WJC level. Of course, their goalies aren't at a future NHL star talent level but neither is Team Canada's most of the time. I definitely wouldn't say goaltending has been a major weakness for the Swiss either in terms of the quality of players or the performance.
Out of curiosity, I looked through Canada's starting goalies between 2010 and 2020 and the only ones with an NHL career are Joel Hofer, Carter Hart and Blackwood. Others are Visentin, Fucale, DiPietro, etc.
