Here's two trades that I'd offer up to New York:

New York In: Lee, JJ, Sullinger, Young, Brooklyn 2016 1st, Dallas 2016 1st, Boston 2018 1st
http://espn.go.com/nba/tradeMachine?tradeId=hah7hop Boston In: Melo, Lopez
New York In: Lee, Johnson, JJ, Sullinger, Young, Brooklyn 2016 1st, Dallas 2016 1st, Boston 2018 1st
Personally, I'd probably due either of these deals, because Lopez would be a nice, defensive big to have at a reasonable rate through his prime. However, I'd prefer the first deal, because then we could possibly still afford a Durant/Horford type this offseason to go along with it. So we'd have:
PG: IT, Smart
SG: Bradley, Hunter
SF: Crowder, Turner
PF: Melo, KO
C: Amir, Zeller
That addition right there actually cures probably 80% of our problems, because it gives us A) another go-to scorer, B) a closer, and C) even more spacing for IT to penetrate. We also don't lose much in rebounding and defense, too, because Melo has always been an above average rebounder.
Now, if we'd add Durant to that core, too? Wow. Here's what we'd have:
PG: IT, Smart
SG: Crowder, Bradley (I did this switch to counter Lebron and the other wings we'd face)
SF: Durant, FA (perhaps Turner at a decent price?)
PF: Melo, KO
C: Amir (unless he had to be dropped to get Durant), Zeller/Mickey
That's a ridiculous lineup right there, and if we could somehow pull off a trade for Melo, it's not all that far-fetched. Could someone check the money? I think we'd still be able to get Durant in this scenario, though I don't know what that means for Amir's non-guaranteed contract.
