Well Brooklyn can only get rid of what other teams actually want. It actually makes sense for Charlotte to go with Joe Johnson considering he's what they wanted out of Stephenson anyway and they won't have to worry too much about the extra space he's going to consume because their team is for the most part going to stay together. Charlotte came into this season expecting to be a top 4 seed and they'd love to take a chance on someone who could possibly put them in a higher tier.
The rest of their contracts that they have sitting around might stay there, because I don't know if there's any takers. Maybe Sacremento might follow through on Deron perhaps, and who knows what Brooklyn gets back on that trade.
