For what its worth I'm starting to see a lot of chatter from fans of other teams suggesting that Boston is the logical choice for Durant.
Doesn't mean he's been linked here, just that people are starting to realize that he could slot right in and contend. Many out there are proposing that all a Durant lead Celtics team would need is an upgrade to the 5 spot and we'd be legitimately the best situation for KD.
Seems like another common sentiment is that it would be good for the league for Lebron to have a legitimate road block on the way to the finals. Nothing to get excited about mind you just a bit of a change in the narrative that he's guaranteed to go to GS or one of the big markets.
Coincidentally, according to Lowe Durant has made it known to some people that Horford would be one of the potential players that he'd like to play with. (http://www.celticslife.com/2016/02/celtics-sign-al-horford-kevin-durant.html)
Combine that with Woj's news that the C's think they have a good chance at signing Horford this summer, and it really seems like the perfect storm to add two excellent star fits to our roster this summer.
Imagine if we could sign Durant and Horford without giving up any assets ?
IT / Smart
AB / Hunter
Jae / Jaylen Brown
KD / KO
Horford /Mickey

I don't see KD starting at the 4. If anything I see Crowder as our new 6th man. With the rumored reports of trying to trade for a star before the deadline I could see another attempt for someone like Love or Butler by draft night that would help lure Horford and Durant in free agency.
Thomas
Bradley Durant
Horford Amir
Smart, Crowder, Turner
KO, Mickey, Zeller
Easily better than any of his OKC teams and you didn't even include the Brooklyn pick.
Maybe we end up with the 1st pick and give OKC Brandon Ingram in a sign and trade. Greatest star player compensation ever.
how could I forget the BK pick? LOL
seriously though, adding a scorer like Durant while keeping our current defense in place? we'd be nearly impossible to beat, and for some time.
I don't think we can keep Amir if we're going to try and land both Horford and Durant.
However, in an earlier thread a week or so ago I think we all came to the conclusion that it would technically be possible to trade for Butler and still sign both Horford and KD to max deals in the offseason. You'd have to do something like this, though:
Trade Bradley, Rozier, Young, JJ (non-guaranteed salary filler), Brooklyn 2016 pick, Dallas 2016 pick, Boston 2016 pick (future picks if needed) for Butler. Then you'd have to waive Amir's non-guaranteed contract and renounce Sully, Zeller, and Turner (I think that's what you'd do with them - not too well-versed on cap holds with pending free agents). This would leave you with the following lineup:
PG: IT, Smart
SG: Crowder, Hunter
SF: Butler,
PF: Durant, Mickey
C: Horford, KO
No more Big 3's for us - it's now the Fab 4 with the mega-jump in the cap! I wouldn't feel right leaving Crowder out of that equation, though, so let's just go with the Fantastic 5!

I do still think we could keep one or more of Sully, Zeller, and Turner somehow, though I'm just not sure how the capholds work in their case. Could someone correct me on that? Is there a way to make the trade for Butler and still have room for max contracts for Horford and Durant, while being able to go over the cap to sign one or more of our own free agents in Sully or Turner? Here's the numbers I used -
