The team sucks because the goaltending has sucked.
With average goaltending they'd be in the playoffs and if Ersson stays healthy they might still make the playoffs even if they trade Laughton and Risto (though they might wait until summer in that case).
It's now 22 games since 11/25, becoming a decent sample size:
They are 2nd in xGF%, 58.06%, behind NJ and ahead of Edmonton (56.87%)
They are 5th in HDCF
They are tied with Edmonton at 1st in GF/60.
And this hasn't been done against the little sisters of the poor:
Vegas, Florida, @Min, LA,
@LA, @Vegas
@Toronto, Toronto, Dallas, 9 of 22 against top 8 teams.
The PP is awful, 29th in GF/60, 32nd in xGF/60.
The PK went south, the worst in the league over this stretch.
So there's a lot of work to do.
And it means they don't need drastic additions, top six/top four upgrades that push solid players down, replace Risto, Seeler and Hathaway the next couple seasons. Add a ST specialist or two. And find a starting goalie. Achievable goals.
