If they lose game 5 in PIT I think AV is basically fired. Putting up that kind of display on home ice is just absolutely embarrassing.
This core needs to be dismantled. Honestly, doing what teams like SJS, PHI (I know they're not very good, but let's look at how bad they were before this year), etc is what needs to be done. There's a lot of talent on this team but a) it isn't being put to use by the coach, and b) it isn't being complimented properly by the GM -- and by that I mean Sather, not Gorton... Not that Sather was terrible in his final years, but that one last offseason he had in 2015--letting AV run the show.... That's where the problem lies.
Still think that AV has a Chip Kelly complex. He literally believes he knows everything about everything, and its not that he's a terrible coach--in the right situations, he's the right coach for the job. In less than ideal situations, he's probably one of the worst -- I've never seen someone be so secluded from making in game changes.
Fire this guy, dismantle this core, and move on.
