Muzzin has been the best defenseman on the Kings this year. Plays in all situations. And well. Is plus 9, best on team, that has a minus 37 goal differential!
It's golfnut, isn't it? Long time, no see.
There's no doubt that Muzzin is having one of his best seasons, but I think that it's really important to factor in Quality of Competition before deciding if someone has been the best on the team. After all, if you're receiving relatively easy minutes, can you really be the best? As I pointed out earlier (but couldn't be bothered at the time to substantiate), Muzzin faces the easiest competition of LA's top 4. I'll get to the graph of that in a moment, but I'll start with 2016-17 to illustrate the difference that it makes.
In 2016-17, Muzzin faced the 2nd-highest Quality of Competition out of LA's D, only a hair behind Doughty. That year ended up being the worst season of his career and he finished with a team-lowest -21.

In 2017-18, he faced substantially easier competition (5th amongst defensemen on the team) and had a bounce-back season, finishing with a +10:

In 2018-19 (this year), his Quality of Competition has remained around 4th or 5th lowest:

Again, this isn't to discount the good season that Muzzin has had, but can we really say that he's been the "best defenseman on the team" when the data prove that he's been getting relatively easy minutes? Put another way, if usages were switched, would Muzzin's season still seem so stellar if he were receiving the toughest minutes and would Doughty's stats not look much better if he were the one receiving the 4th-easiest minutes?
