I'd like to see Shorty Hogue- he was 3-1 against Archie Moore, held his own with Eddie Booker, and I have no clue how he fought or anything else. Except that losing to Charley Burley seemed to finish him as a fighter.
Two other guys: Alberto Davila and Alberto Sandoval. Both were good fighters and both lived near me. I think they'd be champions now and would get a chance to make some money. Davila was 118lb champ, briefly, and still worked delivering Budweiser.
