No way. I admire JCC a great deal for his grit and ring craft, but Pryor possessed a great deal more natural talent. Pryor wins this by a fairly comfortable margin.
As predicted, Valero will soon be pitted against known boxers of any era. And here it is now. As for the question, Valero hasn't really fought any elite fighters so we don't know how he fights at the elite level. So I will go with Pryor here.
He beat 27 bums. His greatest win was over a very green DeMarco. Even if Pryor might be a bit overrated, Valero wouldn't of have beaten the likes of Marquez, Khan, Bradley, Alexander, or even Randal Bailey or Campbell. All those guys would of ko'd that coward.
LOL bailey?? hahaahaa I doubt it seriously! In the end we will never know... maybe the kid would of steam rolled the top dogs... who knows
