There are a lot of FanPosts about trades popping here.

I sugest for everyone to try out the ESPN Trade Machine before coming up with trade ideas.

I don't know if this engine is really loyal to the NBA rules about trades but I think is pretty close.

I'm not trying to take control of anything, I just think that would help making more sense (especially financiary) all the ideas you're coming up to.

Taking as an exemple, the trade that almost happend last season:

The only change is Diop instead of Mohammed (he's not available for trades in the engine), but the salary base its "similar".
