Interesting dialog going on in this thread. I'd like to say that, for the record, if we're going to trade Martin (and not Thompson), so that we end up with 2 picks in the top 4, I'd actually rather see us take Thabeet or DeRozan/Harden.
Rubio/Wall - Beno - Jackson
DeRozan/Harden - Garcia
Garcia - Nocioni
Thompson - Hawes
Hawes - Thabeet
As many have mentioned before, Thompson and Griffin are duplicative talents. If we trade Thompson for another top pick, then we should absolutely draft Griffin, but if we trade Martin, I'd rather we went with Thabeet to round out our front court or DeRozan/Harden to plug the new formed hole at SG.
If, for a very specific and unlikely example, the draft order was:
1. Sacramento
2. Wash
3. OKC
I'd advocate us trading Martin to Wash for their pick, and Griffin (and other reasonable assets) for OKC's pick and Jeff Green. Rubio/Harden/Green/Thompson/Hawes gives you a great young core that is oozing potential at every position.
Also, if Wall were to declare, he's the only player I'd want in this draft over Rubio. Not because I think he'll be a better true point (which we desperately need) than Rubio, but because he'd be the guy with most franchise player potential. The Kings certainly need to plug a lot of holes, but first and foremost, we need the unstoppable franchise guy. We need the guy that the other team gameplans around and says "let's just try and limit him, we can't stop him."
