I think it would come down to Marquez v Pac V or Maweather vs Martinez although if it was m own personal list of fights I want to see there would be plenty more.

Those 4 fighters have to be the most established names in the sport right now, the have all been at the top fo a long time and have beaten all the top guys time after time.

I think Mayweather v Martinez would be absolutely massive what with the size difference and being the middleweight division it would be a mega event. Skillwise and boxing brain I would go for Maweather, Martinez would have the size and strength advantage but that's the onl areas I would give him an edge. That might be all he needs though. Maweather by wide UD.

People will want to see Pac vs Marquez for obvious reasons.
