I’m on the fence where Muzzin is concerned.
I absolutely agree we’d be a worse team on paper if we got rid of him, that a healthy Muzz is our best defender and that Sandin is not now and may not ever be as good a defenseman as him.
At the same time, I don’t trust him to be reasonably healthy by the time the playoffs roll around, and I don’t trust him to stay in the lineup for even the majority of a lengthy playoff run (assuming this team ever goes on one).
So if they dumped his contract now, I honestly wouldn’t be particular bothered by that move. And if they keep him, hopefully that roll of the dice on his health pays off.
