I was thinking about KO too. Here's my proposal:
To SAC: KO and one of Thornton/Prince/Bass, 2015 Clips pick (or 2016 Cavs?)
To BOS: DWill, Stauskas and Reggie Evans, plus we get swap rights for ours and SAC 2015 1st rounders with some very specific protections:
1. Converts to unprotected Kings 2017 1st rounder if '15 Kings pick is in the top 3;
2. Converts to unprotected Kings 2017 1st rounder if '15 Kings pick is outside the top 10.
3. Converts to unprotected Kings 2017 1st rounder if we choose not to exercise the swap (because, e.g., we don't like the choices or it only moves us up 2 slots).
Bear with me here. The idea is that this would move us up in the 2015 draft, probably by 3-8 slots. As of today it would move us from 11th to 6th. This is the difference between the Looney/Kaminsky range and the Johnson/Hezonja/Turner range. (Keep in mind that once we're in the 5-7 range, trading up to the 3-4 range to get someone like Russell gets still easier.)
We only exercise the option if we really like how our options improve. Else, we're basically trading KO and the Clips pick for a 2017 1st rounder and Stauskas which is decent value (and serves their objective of immediate improvement). The Kings are protected in the event they get lucky in the lottery. (#2 is necessary because the pick goes to CHI if it's outside the top 10).
Best of all, it would free us up to pursue the playoffs with abandon and not hurt our 2015 draft position.
Best case we end up in the playoffs AND a top 8 pick. Tankers and anti-tankers unite!
You put a lot of thought in work on this but you'll need to rework your swap conditions as they are affected by Chicago's rights to the pick if it is outside top 10.
1. If in the top 3 and Sacramento doesn't swap, then the 2017 can't be traded. You could do a 2018 pick with language that it conveys two years subsequent of the pick being conveyed to Chicago or do 2019 straight.
2. If outside of top 10, then they can't swap it. It will be Chicago's pick.
3. Depends on 1 and 2 and then you will need the 2 years subsequent to the pick being conveyed to Chicago language.
