Ok, so you are considering Jokipakka a guy brought in to somehow help this team? Fair enough...
So, Dorian couldn't see that we were 1 (ONE) injury away from playing Wideman/Boro in the top 4?
That seems like common sense that you'd want a guy who can fill in, as either of these guys in your top 4 is a hindrance to winning. Many were vocal about this before the season started.
Now, we have our 7th on the top pairing, and our 5th/6th making up our 2nd pair. You can't blame Dorian for all of that, nobody would have ever predicted we would see Boro/Claesson/Wideman/Jokipakka/Harper on the ice at the same time, that's just an incredibly bad string of luck, and what is essentially a deathwish at this point of the season.
But yes, I do blame our management for not addressing a glaring need in both the off-season and trade deadline. Obviously you don't plan for your whole top 4 to be injured, that's foolish, but you certainly, in my opinion, be alright with being one injury away from Boro/Wideman in your top 4 and trying to make the playoffs.
This isn't hindsight, I/many others were clear and vocal about this before the season even started.
