I'm having a hard time coming up with even imaginary solutions.
If I was a fan of another team, I'd be pretty furious with my GM if he traded for Lee, Green, Bass, or Terry (LGBT). Those have got to be four of the worst contracts in the association.
And I don't know why anyone would be anything more than ambivalent about a trade for Sullinger, Fab Melo, Barbosa, Collins, or Wilcox.
The only trade piece of any value is Rondo, only we can't trade him because there is literally nobody else on the roster capable of playing the point.
Really the only option is trading for an even worse contract and there aren't many of those left. Even Biedrins and Okafor have more palatable contracts than LGBT. Maybe we can trade Jeff Green for Kendrick Perkins!
