There has been plenty of discussion about what the Mayweather and Pacquiao undercard is going to hold, and what type of talent it is going to feature. Guesses range between no notable undercard names whatsoever to fights, which could really be there own card, as we saw with Garcia vs Matthysse. My opinion on the best possible fight to precede the main encounter would be Khan vs Bradley.
Sure there are better fights to be made in the sport such as a bout featuring red hot Brandon Rios or something featuring the powerful Marcos Maidana or even a spectacle between amateur legends Vasyl Lomachenko and Guillermo Rigondeaux, but as far immediate affect on the division which includes the names Money May and the Pacman, this one would be ideal.
