Very likely! Just not sure how great of a record it is in this day.

Wiki states:
Over the course of his decorated career, Pacquiao has defeated 22 world champions—Chatchai Sasakul, Lehlohonolo Ledwaba, Jorge Eliécer Julio, Marco Antonio Barrera (twice), Érik Morales (twice), Óscar Larios, Jorge Solís, Juan Manuel Márquez (twice), David Díaz, Oscar De La Hoya, Ricky Hatton, Miguel Cotto, Joshua Clottey, Antonio Margarito, Shane Mosley, Brandon Ríos, Timothy Bradley (twice), Chris Algieri, Jessie Vargas, Lucas Matthysse, Adrien Broner and Keith Thurman.


Now if I were to ask how many great fighters were in this group -IMO I would delete the following:Chatchai Sasakul, Lehlohonolo Ledwaba, Jorge Eliécer Julio, Jorge Solís, David Diaz, Joshua Clottey, Chris Algieri, Luca Matthyse.

On the fence: Adrian Broner ( not over rated, rather under performed)
& Oscar Dela Hoya( totally too shot, hadn't fought at that weight in a good minute- just a name on his notch)nevertheless a champ.


This link gives 15 for Floyd, too lazy to look on--
