Remaining proposals to consider:
1. Martin, Garcia, and Thompson, for Jefferson, Sessions, and Jawai
I’d like this one a lot, if it didn’t involve Thompson and Garcia. I still don’t think Hawes is quite ready for prime-time, so I think keeping JT (as PF alongside Jefferson) is essential. Garcia is a fantastic energy guy, a Swiss-army type that can do a lot (steals, 3s, blocks). I think the Kings give up too much/get too little in return, and as the OP himself confessed, the bench becomes paper-thin.
2. Martin, Garcia, and 1st rounder for Jeff Green, James Harden and Etan Thomas.
Would like to have heard a case made for this one by the OP. Again, I think the Kings give up a lot here. Martin is the player Harden wants to be, perhaps best-case scenario. Would you trade Garcia and a lottery pick for Jeff Green? I wouldn't.
3. Martin and Nocioni for Josh Howard and Jason Terry.
I like this one. A pretty good return for Martin. Terry is a great complement to Evans in the backcourt. Howard is a talent, but also has injury and headspace issues. But neither contract is long term, so Sacramento could test drive this combination for a season before deciding to resign Howard and/or exercise the team option on Terry’s contract. If they want to move on, Terry and Howard become great trade chips. Most importantly, Sacto keeps all its young talent in this deal.
4. Kevin Martin, and expiring contracts of Kenny Thomas, Sean May, and Sergio Rodriguez for Andre Iguodala, Samuel Dalembert, and JJ Hickson
My own submission, so I’m biased. I thought I made a great case for this deal, but it hasn’t received a single vote. If that’s due to concerns about plausibility, I’m not sure how this proposal, based on persistent rumors of McGrady for Iggy and Dallie, is any less plausible than the Gallinari or CP3 proposals. If it’s about net gain for the Kings, they turn Martin into a superathletic wing and a defensive center with one year left on his contract (huge trade chip next season), while keeping all their other young personnel intact. Defensively, a five-man unit of Evans, Iggy, Casspi or Garcia, Thompson, and Dalembert would be sick, but would not struggle to score. Improved defense and slight decrease in scoring is a net gain over keeping Martin.
I think it’s poor taste for vote for myself here, so I vote for the Sacto-Dallas trade.
