Depending on the new CBA, I wouldn't expect much. If the new CBA is similar, he will still be a MLE or less player, which means teams can sign him without doing a sign and trade.
Sure, there can be benefits to a sign and trade, but no one is going to give up anything too valuable for that.
Our best chance is to trade him for someone the other team has no interest in bringing back themselves. Either someone with a bad contract, or someone who is asking for more money than they are worth.
