As ugly as it looks on paper and though it could be better, the defenseman/lack of defensive depth weirdly hasn't really even been the main issue, for the most part (the depth defensemen have been okay, and a #6 guy like Burroughs actually looks outright fantastic). It's been the defensive play of the expensive high-minute, go-to guys like Hughes, Miller, Horvat, Boeser, and Hoglander, who have been absolutely terrible in their own end for some reason (and seem to have turned Demko into a bit of a panicking nervous wreck expecting to be hung out to dry at every turn, in the process). Only the Pettersson line and the fourth line have been a non-liability defensively. The coach's inability to be smart about who to deploy given how they're playing has a lot to do with the losses as well.
Also, all the "nothing quiet about it" people are missing the joke.
