This is sort of a combination of some of the other recent proposals....sort of.
Boston trades KG to OKC for Perk, filler, and the #12 pick. KG theoretically puts the Thunder over the top and they may see the 12th pick as a reasonable price to pay for that.
Then we deal Pierce(and they use the buyout option), Bradley, Sullinger,picks 12,16, and our pick in '15 for Love and filler. This of course depends on the idea that Love is currently stomping his feet demanding a trade and they relent. That's not a great return for an all-star big but I've seen worse.
So our new core would be Love, Rondo, Green basically.
Edit: And of course I'm aware of KG's no-trade clause, though this would present him with a realistic chance at a few more rings before he hangs 'em up.
