I also have to agree. Our rising stars will just probably stay in their current division. If there's a possibility to move up, only a single division up and that's their final division, or maybe will revert back to their comfort zone. Manny Pacquiao is the only boxer that surpasses the weight division that a Filipino boxer can. It's a blessing for him as in terms of bodybuilding, we have limits as mentioned above. Unlike in European or Western countries, a baby has a chance to bout at the heavyweight class in the future, with or without forcing it to happen. We didn't even think that someday famous boxers like Oscar Dela Hoya, Shane Mosley, Ricky Hatton, will be faced by a Filipino boxer and even knocking them out.
Nonito Donaire, John Riel Casimero, Brian Viloria are some of the examples of those Filipino Boxers who are popular and the best "only" on their respective divisions.
