Which featherweight (126 lbs) boxers historically could defeat at 100% Rafael "El Divino" Espinoza for you ?
Khegai is shorter than Armstrong and He didn't have any issues hitting Espinoza. I don't see this being a problem. Gamboa would have more of a problem due to being primarly an outside boxer, perhaps.
Khegai was fighting to live another day, he had lots and lots of issues. The fight could've been stopped at around RD 7 and it wouldn't have changed anything imo.
Sure, but that's Arnold Khegai. Fringe contender outside of division's top 10. We're talking about Henry Armstrong. I wonder who was the tallest guy Armstrong beat in his career? Maybe someone here will know. Zivic was 5'10. I don't see extra 3 inches - not backed up by great abilities - making that big of a difference.
