I would say that Danny Granger probably makes the most sense out of all the options, especially if the Pacers feel that Paul George is a forward and only a forward. Financially, they're in great shape for the long-term, so re-signing Hibbert/George/Collison won't be an issue anyway, but... if they want to acquire a big name SG to pair with George (Eric Gordon, Kevin Martin, etc.), then moving Granger might enter into their minds.
Ed Davis, James Johnson, 2012 pick might be enough... I don't think we would sacrifice DD in this scenario.
As for the others...
- Josh Smith is probably the 2nd most likely option, although he doesn't really satisfy the 3-point shooting criterion that BC/DC are looking for from the 3 spot.
- Rudy Gay is wayyy too valuable for the Grizz IMO.
- Ditto for Deng.
- Ditto for Parker.
- Iguodala might work, but I just don't see much incentive for the Sixers. (And like Smith, shooting is not his strong suit.)
After that, I don't think anyone else in their salary bracket is really worth trading for.
