Well i would take Hagler over Zale definitely, not in any disrespect to Tony though. Most people will take Hagler over Cerdan on the grounds that Cerdan's resume doesnt imply he may topple Marvin. Not for that reason but istill take Hagler in a war, both of these fights are wars,i just think that Cerdan makes it closer,prime Hagler would be given more trouble in attempting to box Cerdan than Zale. But Hagler would come through imo.
cerdan fought a lot of his career at welterweight and may have been past his best when he beat zale.there was talk of him and armstrong fighting. couldn't see either of them pushing hagler !!
