I wouldn't want to see either because when Hopkins fights really really tough competition he becomes even more boring. Actually last night was one of his more entertaining fights in recent memory... Worst is the fight against Winky probably... And the Calzaghe fight wasn't that fun to watch either. At this point I think Hopkins would beat Roy but lose even worse against Calzaghe in the rematch but the fight would still look ugly.
B-Hop has nothing left to prove imo. I don't think he needs Chad Dawson and he can comfortably retire if he can't get rematches with Jones or Calzaghe.
The only Hopkins fights that would interest me are against Calzaghe and... James Toney.
Very simply, I'd like to see Hopkins fight the winner of their fight. If that fight for some reason doesn't happen, then I'd like to see Jones-Hopkins II more.
Hopkins-Calzaghe was one of those fights that had to take place to answer questions but it's not something I'd like to see again.
Jones-Hopkins II has a lot more intrigue to me.
