I could talk myself into any of the names mentioned thus far, assuming the price is right.
Afflalo has made sense as a Kings target for a while now. Maybe SLIGHTLY less so since McLemore started improving. I would worry about stunting his growth with Afflalo here, particularly because Afflalo's contract is basically over after the season. He could pop in, take McLemore's spot as the starter, play 30 games, and leave. I don't know what the Kings are getting in that scenario.
Wilson Chandler is also kind of interesting, and at least he's under contract for one more season. I'd say he's a little more versatile than Afflalo in the sense that he's played a little SG and PF in the past, and he's more accustomed to coming in off the bench. Afflalo has been a consistent starter since his third year in the league. Chandler can be moved around a bit. Decent player, but again, I'm not giving up anything of major value for him.
I'd put Ilysova in the same camp as Chandler. Decent. Versatile. Under contract ... not worth a real asset.
Jerebko is name I like hearing. He should come at a cheap price, and I still feel like there might be a player there. A small gamble.
