I'll be surprised if Jones-Hopkins actually happens.

1. I don't think Jones would risk fighting Hopkins again. As it is right now, he can go into history saying that he beat Hopkins. Why give him the chance to even the score?
2. For this fight to happen, Jones and Hopkins would actually have to come to an agreement. Jones and Hopkins may be the two most stubborn people in the entire sport of boxing. I just can't see them getting to the bargaining table and agreeing on something.
