The real thing we should be hating here is the make up of the roster IMO. Lets face it, with what we would consider a better coach, we barely made the playoffs last year, and have been out in round 1 the last 3 years. There are bigger problems here than the coach. It's the roster. Z and Pav are shells of their former selves. The D-men are... bad. There's a lot of "good" players on the roster, but that's it. Nyquist, Tatar, and Jurco are great examples of that. Good... but it doesn't look like they're going to get beyond that. They'll never carry the team like we expect them to.
Now did Blashill make some mistakes with lines etc... Yeah, maybe. But there's an easy argument to be made for just not having enough goal scorers on this team to get the job done in the playoffs, against Bishop, a guy who's bigger than the damn net.
