I don't like most of these. Let me put down what I would consider a summary of the trades, leaving out players I think are truly irrelevant salary dumps:
1) Kings get: 2019 WAS 1st-rd, 2 2nd-rds
Kings lose: WCS, $27M
So...give up on Willie and spend $27M to get one marginal first rounder? No chance.
2) Kings get: 2019 POR 1st-rd, Layman
Kings lose: Skal, $20M
This is not so bad. We're paying some bad money for Leonard but if Layman can actually give solid minutes at the 3 (I'm not sold) then it's workable for me.
3) Kings get: 2019 POR 1st-rd
Kings lose: Kosta, $28M, 2 2nd-rds
Compare this to trade #2 to see just how much worse it is. I have zero faith in Evan Turner being an NBA-quality player, so...NO.
4) Kings get: 2019 MIA 1st-rd, Tyler Johnson, no more Z-bo
Kings lose: $32.5M, a 2nd-rd
If we had any possible use for Tyler Johnson, who is a decent but overpaid player, maybe. We have no use for Johnson. If worse comes to worse we can just waive Z-bo. So it's basically $32M for a first rounder. That's a seriously stupid overpay.
5) Kings get: Harkless
Kings lose: WCS, $33M
I kind of like Harkless. I don't like Harkless anywhere near that much.
6) Kings get: Wiggins, no more Z-bo
Kings lose: Have to pay Wiggins $146M
This is the Russian Roulette of trades. We need a SF. Wiggins is 23, under (expensive) control for 5 years, and a former #1 overall pick that plays SF. But he hasn't been good. If our talent evaluators can come back and say, "Look, the kid has got what it takes, but he's been misused in Minny. He fits the system we want to put together anyway, and we can seriously build with him as a piece, and I promise he'll look like a top-5 pick within a year or two", then pull that trigger and hope the chamber is empty. Otherwise, pass. You just can't lock up a quarter of your salary cap for five years on a guy unless he's the real deal. My inclination would be to pass, but barring one of the other trades stumbling into a pick that hits the lottery, it's really the only deal that has a chance of being a championship-delivering deal. It just has a huge chance to bury the franchise as well.
7) Kings get: Wiggins
Kings lose: WCS, have to pay Wiggins $146M
This is way worse than #6, so it's not even worth considering if #6 is on the table.
So, to sum up: The only deals I would even look at in this bunch are #2 and #6. #2 is kind of an overpay on Layman in trying to stopgap SF for a few years, with a pick. It's not a disaster, but I don't think it would really move any needles in the end. #6 is a true high-risk, high-reward, high-catastrophe bargain. If we really truly think that reward outweighs catastrophe, then I'm intrigued (but reward probably doesn't outweigh catastrophe).
