I've been a Pettersson fan since his days in the SEL.
He is straight up costing this team the season with how he's playing.
You cannot have a top line center suddenly stop all production. The entire team dynamic is thrown off. It's way more impactful than Demko being injured IMO. And what's worse is that he's not even playing aadequately in his own end either.
There was a play towards the end of the game where Pettersson was barreling towards Lauzon (you know, the guy that threw the cheap shot) and instead of running him into the boards, Pettersson stumbled awkwardly into a weak check and got tossed to the ice like a bag of pucks. That was so f***ing pathetic.
