Our most enticing non-Rondo package would probably be Green, the 3 non-guaranteed deals, our #16 pick and Sully. That's in the general ballpark of what OKC got for Harden (Martin, Lamb, Toronto pick).
Problem is there really isn't a Harden level talent on the market. Cuban has promised he's not moving Dirk. Minnesota is trying to pull themselves out of the bottom of the barrel - they are not going to dump Love for another rebuilding package unless that situation gets a lot worse.
Harden wasn't a star when that trade was made. He wasn't even a starter. They were taking a chance and projecting him to be a star.
They got Lamb (picked 12th), Martin (a solid starter who averages 18 points), two future 1st rounders (one of which comes from Toronto and is projected 12).. plus a 2nd round pick.
Sully wasn't a lotto pick. The #16 pick isn't a lotto pick. Even if we pretended those two were lotto picks, to equal the bounty that OKC got for their bench player, we'd have to find another 1st rounder and a 2nd rounder.
So in other words...
it would be like packaging Jeff Green, Sully, the #16 picks... another 1st rounder... another 2nd rounder... and getting back a bench player with potential. Derrick Favors, for instance. Except that the Houston package was more valuable than that imaginary Boston package.
The prevailing wisdom was that Harden was a bonafide all-star talent - he was widely viewed as the 3rd or 2nd best player on a team that went to the finals. The whole reason OKC traded him was because they both knew he could get a max deal on the open market.
Calling him a "bench player with potential" is misleading semantics - he was valued as a young star.
I hadn't realized that OKC got an extra 1st round pick in the deal, so I'll throw one in to the theoretical Boston package to return to the comparison:
Green + Sully + #16 + future pick is in the general ballpark of the deal that landed the 2nd or 3rd best player (and young to boot) on a finals team.
Of course, these kind of trades don't happen in a vacuum (a Green centered package is best suited to attract a team with a hole at the 3), but the point is, we have the talent to put together a trade for a star.
The question is whether the right star will become available. And I'm pessimistic on that front.
Dirk would be intriguing (a Rondo/Bradley/Pierce/Dirk/KG line-up would be loads of fun), but Cuban has been adamant that he won't trade him.
Kevin Love might be available but given Minnesota's recent history, I have a very hard time seeing them moving him for anything less than an established star.
LaMarcus Aldridge might be available, but Portland would have little interest in Green with Batum on board.
There is a second tier of stars that might be more attainable though.
Josh Smith in a sign and trade (and Atlanta has a pretty massive hole at the 3).
Pau Gasol (in a deal centered around Pierce or Green).
Anderson Varejao (for Green)
Demarcus Cousins (valuation on Cousins varies pretty wildly, but I can see the Kings valuing a Green/Sully + package highly).
