I kinda agree with NHL 12 on raw value on the Carter deal, but putting him back with Richards is really fascinating. Johnson is a massive piece to lose -- they have to plan to add some more to that blueline, given how bleak it looks now -- but while some of their offensive issues are system-related this is a huge step for a team that's finding ways to win in spite of not really scoring at all. It's funny how much better this forward core looks compared to last year now, in spite of how bad the GF column for the Kings looks: Richards, Kopitar, Carter, Brown, Gagne, and Williams is a pretty ridiculous top 6. I don't think it's a team ready to win this year but Richards, Kopitar, Carter, Brown, Doughty, and whichever of Quick/Bernier they decide to keep is definitely a core they can win cups with and they're all pretty young. The cap hits are pretty managable(except Doughty...) for their abilities, too -- the skaters + Williams is only running them 28.47, which isn't bad considering Ovechkin alone is 9.5 in Washington. They have plenty of room to add pieces, especially once Penner's 4.5 comes off the books after this season, and with the six forwards I mentioned plus some other nice pieces like Stoll and Loktionov they're probably only a couple small adds and switches away from being there with the forwards.
The blueline, though... obviously Doughty was always going to be their long term #1 guy there, and they get underrated defensive games from Greene and Scuderi, but there's just not a lot of offense after Doughty. Voynov has been really, really good offensively in short appearances this season so I can only imagine he's in the bigs for good now but even with him I feel like they need another offensive D and another depth defensemen before they're playoff rush ready... and even then Doughty would lack a partner of equal skill(at least until Voynov is ready for that role). They seem to get closer every few months... surprised they're not winning more.
Also you know who this doesn't make sense for? The Blue Jackets. Remember Voracek and the Couterier guy they traded for Carter? Yeah....
