Yea, Amico MIGHT be the worst 'source' out there, but something is clearly going on between SAC and CLE.
Also, Deng can't be dealt with anyone else, but the Kings could offer something like Thornton and Williams, Thompson and Williams, Thompson and Outlaw, etc .. it's mostly just garbage though, unless they do something nutty and trade away Gay for Deng just to dump the capspace and go after someone in free agency.
I'd be quite excited if all these talks eventually led to Varejao.
