The only reason we even compare Corrales and Castillo to Hearns and Hagler are that Hearns and Hagler had a great fight and so did Corrales and Castillo. But added to the great fight Hearns and Hagler had, Hearns and Hagler have hall of fame credentials and wins.. Hearns fought Cuevez, Benitez,Duran,Leonard,Hagler, Hill, Barkley. Hagler fought Hearns,Duran,Leonard,Antuofermo,Mugabi. Corrales and Castillo lost to guys who were not the caliber of Hearns and Hagler and Duran and Leonard. There is no comparison. The resumes say it all. What Corrales and Castillo have is a great fight.. That is good. most guys do not have that.
