Langford fought the number 1 WW fighter in the world in 1904. He had turned pro 2 years earlier he had a record of 21-2-10 one of those losses he avenged. He stayed at WW for another year before outgrowing the division. He left the division at 23 years of age. Quite often this is used as proof that we are dealing with a Langford who is green as grass. Hearns fought the number 1 WW fighter in the world in 1981. He had turned pro 4 years earlier and had a record of 32-0 Quite often people say zhesnrs is better as a LMW and at WW he was slightly pre prime. I'd argue that neither fighter was at their peak as a WW and thus any dis advantages due to being green are negated. With that in mind I'd say it comes down to the style clash. Hearns is a rangy aggressive hard hitting monster with rapier quick hands. Langford is a tank who probably has the best counter punch timing in all of boxing history. A tall aggressive fighter known for having a weak chin against a counter puncher who's perhaps the hardest hitting fighter to ever grace the division. I only see the fight ending one way. Langford by ko. The other weights speak for themselves.
