The best thing for the Sixers, and possibly for Ben as well, would be to wait and see. It just depends whether Rich Paul is willing to work things out if he can't get what he wants (because the Sixers won't give it to him if it's a bad trade, and Paul can't make a better happen).
If not though, I don't see how the Sixers can go forward with Ben holding out, so the question is could everyone really smooth things over?
