What about Eric Gordon, a 2016 first and a 2018 first for Humphries and Bradley?
It gets them out from underneath Gordon's contract, and Bradley is arguably a more impactful player than Gordon when you take defense into account. Humphries is better than any center option they have on their roster right now unless they play Davis out of position. They can make a run at the playoffs this year while also clearing enough cap space to be active on the FA market this upcoming offseason (if I'm not mistaken).
For us, we take on Gordon's awful contract in exchange for a couple of future firsts. New Orleans is likely competitive by that time, especially if they add a big FA to their Holiday/Davis/Anderson core. That means the picks are likely late firsts, which is why I'm demanding two of them. There's also the chance that Gordon regains the form that earned him his current contract, which isn't a bad risk to take for a franchise in our position.
Feel free to toss us Ajinca as well if you think we aren't getting enough, though I honestly don't know how he's regarded as a prospect.
