No offense but that is a horrible plan. Basically a minor upgrade on defense but we are still short a top 4 defenseman. And Yak is a downgrade to Pearson.
You're great idea is letting Lucic walk, signing Yandle and running Muzzin/Doughty Yandle/Martinez?
Problem 1: Sutter is not going to run a Yandle/Martinez pair. (I doubt Sutter will put Martinez on the top pair either.)
Problem 2: Expansion draft. You are now protecting 3 of Doughty/Muzzin/Yandle/Martinez. (Kings need to add assets, not lose them for nothing.)
Problem 3: Let Lucic who is productive and wants to play in LA walk for nothing when the Kings need to add assets.
Yak is a gamble. Pearson is currently the better player. Yak if he can figure it out has much more skill. Kings are at a point where they need to pull things out of their *****. Putting Yak in a structured system could really pay off. Plus Sutter would get an ulcer coaching Yak. Not to mention the Kings have a ton of wings coming. Besides Sutter doesn't even play Pearson in the top 6 regularly.
The more I crunch the numbers it looks like move Toffoli/Martinez for cap reasons. Toffoli is a 30 goal scorer (on the Kings) and has a cup. Martinez has 2 cups. The Kings should be able to get some good assets back. Also moving Toffoli solves that inevitable 5-7M contract he'll sign.
They could move Brown, but that would probably cost assets instead of returning them.
-Need number 1: Solid RHD for the second pairing. There are not a lot of these players out there. There are fewer for trade. This is the hardest position to fill so it's the first as far as importance goes. The Kings are also competing with EDM for RHD, who will be dangling Hall/Eberle. This is why I threw out Toffoli for Barrie.
-Not being able to fill that offensive RHD: Sign Yandle, and a defensive RHD. Now keep in mind with Muzzin/Doughty, Yandle/???? the expansion draft, not to mention the cap. The Kings may have to sign someone like Schenn to fill that spot initially. It may take more then 1 year to fix the top 4. Kings don't have the cap space and the expansion is coming.
There's going to be some youth on the team next year to make the cap work. It would suck losing Toffoli and Martinez, but the Kings need to add assets, with no first this year and tanking's not really an option. The only way to do this is through UFA, which means the Kings have to move salary out, and trading players not named Clifford/King/Nolan/McNabb because mid to late round picks don't help and neither does saving less then 1M per player when you factor in their replacement.
