Has there been a boxer more naturally talented than Earnie Shavers?

You mean natural power?Natural talent & power are two way different things.Remember first time I heard about shavers was awed by his power but the more I studied him learned he was a bit if not vastly overrated.Not saying he's garbage but people put too much emphasis on his KO power if you look at the comp he was fighting it's really not that impressive.As soon as he stepped his competition to people that could match him he would not only get beat himself but ko'd.Anybody with decent power can look like a monster fighting taxi cab drivers,hence deontay wilder 25 wins(25 ko's)As soon as he steps up his comp expect him to not only lose but get exposed & ko'd as well like seth mitchell ect.
