Has there been any fighters in history that has moved up in weight like Pacman and won? I can only think of RJJ vs John Ruiz. Diego Corrales moved up from light to wealter and got smashed by Clottey.
Jimmy McLarnin is probably most similar to Pacquiao. Started out early at Flyweight, moved through several other divisions, and became Welterweight champion. Defeated a lot of great fighters along the way. There have been several others that have moved into new divisions with the same success, and more that just fought opponents no matter the size difference (Sam Langford and Joe Walcott probably being the best examples).
Armstrong jumped from feather to welterweight and beat ATG Barney Ross. Guys like the Barbados Demon and Sam Langford did it on many occassion, also Fitzsimmons went from middle to heavy and won the titlt beating Corbett.
The Tijuana Punisher moved up from jr. lightweight all the way up to light heavyweight and won a world title. ATG he is.
Duran, starting out at Bantamweight, dominating Lightweight for 7 years, Welterweight champion, Jr.Middleweight champion, and 17 years after he won the lightweight crown - Middleweight champion. He also beat Jorge Castro, a solid fighter, at Supermiddleweight when he was in his late 40's.
I was going to say the same thing. What a noob thread. His next endeavor: "Has der evah been any fightas dat was strong?"
