LOL okay. Now you're just conveniently forgetting that he had bad turnovers deep in Kings territory, passing to opponents in the slot. And by the way, that's absolutely not quantifiable in advanced stats because 1 boneheaded play is going to be negligible statistically, especially if the goaltender makes the save. But whatever, everyone else here can remember it. Or just watch highlights of the Blues series in 2013. That may refresh your memory.
And nobody here is saying that Muzzin was a "terrible defender". You can be a good defender and make mistakes. Most people here are saying that you know, young players can improve with experience. If I'm remembering wrong, I apologize, but I'm fairly certain you were one of the posters here who were negative toward McNabb from the jump. Even saying something to effect that he wasn't an NHL caliber defenseman. Any time someone brings up Muzzin as a good example of what a young Kings defender can become with development, you seem to have a problem with it. But whatever, we all root for the Kings and it's strange to have this discussion after a nice win. I'm about the name on the front of the jersey, not the back.
