Not at welter nor did he ever win a world title at welter, nor did he knock out a light heavy, nor did he go toe to toe with Hagler, nor did he spark Duran in two rounds, Hearns developed into a much bigger fighter than Pryor, no comparison in their careers at all.
It doesn’t necessarily have a bearing on the outcome of the fight, but to any real fighting man if you get done in sparring, then you count it you don’t just write it off as only sparring, it gets to you it bothers you. But how it influences you in the fight is down to the individual fighter, so I would say it does influence the outcome of the fight but how it does comes down to the individual fighters
At the time they fought in the amateurs, Pryor was the better fighter. They never fought in the pros, where Hearns fought at welter and developed into a bigger fighter in the higher weight classes. Both were outstanding and good people to talk to.
What did they say to you? I found Nigel Benn to a very nice person when I met him when I was 12 years old.
