Did the pacquiao-julio cesar chavez fight really happen? somebody out of his mind perhaps is fantasizing it.?

NO it didn't. Pacquiao came a decade later, some years well past Chavez's prime. The best weight where they could be made to fight in a fantasy boxing would be the junior lightweight where both really made their marks, with Pacman lingering in that division for at least three years. In that fantasy fight, I will go for Chavez by a close but unanimous decision. Chavez never lost in that weight while meeting and beating many of the best including Hector Macho Camacho, Bobby Chacon, Mario Martinez and Bazooka Limon. But while Manny lost one to Morales, he rebounded well by beating Morales twice by KO, beating Barrera again and finally defeating Juan Manuel Marquez for a share of the world crown. But up against a prime time Chavez, Pacquiao would be forced to fight on the defensive with Chavez chugging along seemingly unpurturbed by Pacman's jabs and hooks. Pacman is never effective fighting backwards and that would make the difference in the judges scoring. Chavez face would however be a bloody mess by the end of the fight.
