Depends on your definition of superfight. I'd argue any time 2 people in the top 10 p4p lists fight each other it's a superfight. Donaire-Rigendeux was Definitley one. What else can be made that's better in that division? Floyd v Hatton and JMM was. Pacman v Hatton and JMM 3 and 4 were.
Just recently we have had some solid fights between very highly regarded world champions: Ward Dawson Mares Moreno Alvarez Trout Donaire Rigondeaux Super fight status is a debate in itself, what constitutes a super fight? is it revenue generated? is it the fighters status's? what? Because if you ask me the above 4 fights are super fights even though they didn't deliver what you would describe as legendary, memorable moments, they were still top draw fights! If you like that sort of thing
If Vitali done a Ryan Giggs and shagged Wladimir's bird (Hayden Panettiere) we could have a super fight with the two Klitschko brothers. The PPV would be £50 and people would still pay it! Cant see it like lol
