1) I'm not a capologist but I'll do my best and would appreciate any additions or corrections from knowledgeable nontrolls.
2) We trade for Butler and max Durant and Horford.
3) Our four stars (Thomas plus the three new guys) would be approximately $76 million of the probable $92 million cap.
4) The trade for Butler would be Crowder, Bradley, Young and #3. This is an overpay but allows you to get Horford and Durant here. The cap situation probably won't allow you to keep either Bradley or Crowder.
5) We have to let Johnson, Jerebko, Turner, Sullinger, Zeller, and Holland (bet you forgot about him) just walk.
6) That would leave about $11 million left in guaranteed salary: Smart, Olynyk, Hunter, Rozier, and Mickey. This would give us 9 total players for $87 million and $5 million left to sign draft choices and fill out the roster with minimum wage guys. If that's not enough we can always move someone like Olynyk for a future draft choice, though I prefer not to.
7) The cap will go up again next year which will allow us to fill out our rotation with some veterans plus Brooklyn 2017.

This is, of course, based on the idea that Durant would come here if Butler and Horford are brought in. That idea may be entirely false.
