A super fight cannot be as simple as two champions because a champion could be a one time deal or a champion could even have a losing record or a very mediocre record.
A super fight would be between two fighters considered near unbeatable and having proven their longevity not just unbeaten over a few fights.Then you have to consider the fights they won,are they legit fights or gimme fights.
An example would be Silva he is the exception here because he did prove a long unbeaten streak but the argument one i have always used was he was given easy tailor made opponents.It would be like giving GSP fights with guys who have zero take down defense,they would be easy fights.
Weidman is on his way to proving himself a super fighter but not quite yet,he has to face a few more versatile fighters.Then if he was to face someone of equal status it would be a super fight.
Barao was before losing considered a super fight prospect because he looked unbeatable.I cannot say the same for Aldo because like Silva he never really fought anyone who would try to take him down.That one exception happened when Hominick took him down and imo and many others would have defeated Aldo that night if not for the bell.
Jones is another in the same line as Silva and Aldo,he also looked to be that untouchable fighter until he was matched with equal size ,then he looked like a mere mortal.I can even go back to the days of Matt Hughes,he was simply bigger than everyone else at 170,then when GSP decided to put on added size he made Hughes look bad.
Point being there has been VERY few fighters anyone could give the status of super fight potential.
