Dallas: Rondo
Charlotte: Green, 2015 Clips pick from Boston
Boston: Stephenson, Wright, Felton (have to eat his contract), 2015 Charlotte 1st round pick (maybe top 2 or 3 protected), 2015 Mavericks 1st round pick
We do it to take a flyer on Stephenson, who only has one more guaranteed year after this season, and we hope and pray he can put it back together being the main ball handler in a terrifying defensive backcourt with Smart. Hopefully he turns into a reclamation project just like Turner, and if nothing else we have a TON of expiring contracts in 2016. We're not competing within the next couple of years anyway, so why not try it? We also get Wright as a decent backup and expiring contract, but we'll have to eat the Felton contract. We also upgrade the Clips pick to a likely lottery pick, and we add a third 2015 1st from Dallas that we can try to package for a top pick if we don't get it ourselves.
Dallas does it because this is basically what they're offering right now: Wright, Felton, and a late 1st.
Charlotte does it because they've been shopping Stephenson, and everyone believes they'll have to attach a first to him to ship him out. Green is a major upgrade from Stephenson (at this point), and he'd work great in Charlotte. They also don't lose a 1st round pick but merely take a lesser one.
Do it, Danny.
