This is a nasty little matchup. Two compact wrecking balls, 15 rounds. And it's Langford s era and rules.
Oops. Didn’t read the entire post. I’m going with Langford by KO if in his era. Qawi wouldn’t have been as slick back in those times.
Qawi would beat him to the punch, better technique, probably quicker and more co-ordinated, punches off of his defence more smoothly etc, he’d be a step ahead at all times.
