Kings have only given up 1.56 GA/gm, 2nd only to winnipeg's 1.52, since the Four Nations....that's when they put together lines and d partners that made sense.
Yet, as good as their D personnel are, they have some big weaknesses. Kings' D is a great as a team, but individually, the D foot speed SUCKS, and they can get physically overmatched as well. The forwards help a lot here. If they were fully healthy it would be better but Doughty isn't even close to 100% (resting now even) and a few of the others are banged up and can't afford to be. Yet
Doughty-Anderson
Gavrikov-Spence
Edmundson-Clarke
Moverare
Has to be near the top given capabilities, strong blend of LHD/RHD, offense and defense (at least in theory, and lately the offense from D has been coming around). I don't think they've been playing even close to their potential, honestly, especially Clarke post-neutering.
I get the feeling people are still sleeping on Jordan Spence, lowering the ranking, and have always underrated Gavy.
