Pryors chin was not all that people thought that it was. He took illegal stimulants under the guide of panama lewis because lewis knew that pryor would have to take punches to get inside because of his lack of height and reach. Pryor was a talented fighter, perhaps even a great fighter but he didn't possess the chin of steel that people believed he had. He definitely had help. The bombs that arguello landed on him would have hurt fighters several divisions above his weight.
I think Pacquiao would have the best chance. Not only does he hit both fast and hard, but Pryor has been an open target vs. southpaws.
Both very possible, although it's hard to say for sure with such little footage of either one at 140.
That would be 9 fights, and you're twisting stats to suit. Let me add my twists. In his last 29 wins before Pryor Young had 22 stoppages. The man could punch, but like Shavers (on a much lesser level of course) didn't have the ability to take full advantage of it. Alex Ramos was another of the time with superb power who couldn't make it pay. His KO ratio is nothing special tho young's is fair at 60% odd. Box rec stats are no substitute for being in the thick of things at the time or researching deeply. At one time he was 17-2 with 16 ko's and Ring noted "hook and right cross carry knockout power". He was trained by Harold Weston, Sr. He dropped two close decisions to Hearns in the ams, one in a national final.
How can you comment on a fighter that you admit you never really saw but those 2 fights toward the end.
Bobby Joe Young was a good puncher and Pryor was KO'd by a headbutt anyway. But I agree that the likes of Duran, Williams, Napoles could score a KO against Pryor.
It looks to me like it's the combination of punch and headbutt that got Ryor so dazed against Young. On his best day I don't think anyone stops The Hawk at 140, though there's a few that would beat him.
How many Bobby Joe Young fights have you seen? Pryor came off a 3 year layoff to fight a brutal puncher at a weight class he's never fought at before?
The truth is that Pryor's natural weight is 135 pounds. It is only because his best win came at 140 people forget he was even quicker and harder hitter at 135.
