Ok, to clear cap space allocated to top 6 wingers, in order of priority:
Option 1: Dump Brown - need a miracle.
Option 2: Let Lucic walk - would be shocked.
Option 3: Dump Gaborik - pretty good bang for his buck at this point, with ~zero trade value.
Option 4: Trade TT
Lucic is a UFA, and Gaborik is going to be 35 next year. I don't do option 4, unless you get that #2/3 defenseman, which would be difficult. I doubt the Kings can even break even with Brown, one way or another. He's going to cost the Kings something of value, either a top prospect, top pick, or just not being able to add anyone.
#2 or 3 would be the way I go. Trading Gaborik means dealing with other GM's, and we get back to the squeeze again. Letting Lucic go would be the toughest in terms of what you gave up for 1 playoff win, but it would also be the easiest choice in terms of not having other GM's force you into a corner.
All these scenarios probably depend on whether or not fans have mentally prepared themselves for it not being 2012-2014 anymore. This time last year, I was for an all in plan. It was only a year removed from a Cup, and the 14-15 seasons was an odd one in many ways. Now it's 2 years removed, that much more money has been invested in guys like Kopitar(not good or bad, just what is), everyone is another year older, there's going to be a significant hole up front or on defense to start the year no matter what Lombardi does, etc.
More and more, I'm thinking don't even get crazy with things. Let the free agents go. Sign a guy or two on 1 year deals. You got your 2017 pick, so if you suck, you at least get a high pick. You don't have to spend to the cap. Lay low, let some AHL guys get a chance, give Toffoli and Pearson more ice time, and see how the year goes. If things look good at the deadline, maybe do something.
