I think proposals for trading KG are a little absurd unless he publicly waives his no trade clause before the deadline.
These proposals would be under the assumption that KG was willing to leave the Cs and ring chase for the next two years.
I proposed of sending KG to his HS hometown Chicago, reunited with Thibs. It would be under the assumption that Rose would be fully healthy for a playoff run. The Cs could ask for Taj Gibson, the rights to Nikola Mirotic, who projects to be a very good NBA player, Rip Hamilton and Kirk Hinrich for money ballast to make the trade work. The Bulls would also get Wilcox and Barboza.
Giving up Gibson and Mirotic would be a high price for two years of KG, but it could mean two championship. Since the Bulls acquired those two guys with late first round picks, the assumption would be that they could re-stock their prospects the next two drafts.
Regarding OKC, if Presti wanted to guarantee a title this year, he could trade Perk, Kevin Martin, Lamb and a pick for KG and Jeff Green. They lose some three point shooting from Martin, but they get a big body to try to cover Lebron if Miami makes the Finals. KG and Ibaka together would be incredible defensively. The only thing OKC would be missing is a big body to play one on one against big centers, like Gasol, D Ho and Duncan, but KG can hold his own in the low post, and Thabeet can provide a big backup body and sic fouls when needed. Collison is undersized but does a good job competing with bigger center.
Another option would be to bring Dallas into the deal. The Mavs are desperate to clear out cap space, and would give up value to move Marion's money for next season. Marion comes to Boston, Mayo (who is going to opt out this summer and become a UFA anyways) to OKC, Martin and Lamb to Boston, and KG to OKC.
KG would make OKC the favorite to win it all the next two years. They'd have to find a cheapie bench wing this summer, which shouldn't be difficult. Their big group of KG, Ibaka, Perk and Collison would be the strongest in the league.
