Wait guys what if they tried this for a couple games??
Turcotte - Kopitar - Laferriere
Fiala - Byfield - Kempe
Moore - Danault - Foegele
Lee - Thomas (Lewis) - Jeannot
Byfield can't play 1C until he figures it tf out - So play him at 2C but still set him up for success by giving him two very good wingers with lots of offensive potential. Turcotte and Laferriere have been the team's two best/most consistent forwards so you reward their strong play with an opportunity to play more minutes on the top line with a good/responsible C in Kopitar. That also gives Kopi two young wingers to look after which usually causes him to elevate his game a tad. Turcotte becomes the puck hound/playmaker, Kopitar brings the strong 200ft game & composure, and Laf brings some scoring touch.
Then on the 3rd line, those three guys are all slotted where they realistically should be. All 3 of those guys are perfect 3rd liners but ideally aren't playing higher in your lineup (mostly due to lack of scoring potential). Let those guys play a shutdown/energy role and if they score some points, hey that's great.
I don't love the idea of splitting up Foegele - Turcotte - Laferriere but the Kings need to find a way to get some of their other players going and ideally need to get Byfield back to center ASAP (even if he's making some mistakes). This gets Byfield back to C and promotes Turcotte into an elevated role (Kind of serves as a "hey sorry we're moving you off center kid you've been great but the rest of our team is struggling so we're just trying to find a way to mix things up").
