People are underestimating The Macho Man here. Though I'd still likely pick Pryor, I wouldn't put money on it.
If what happened to Camacho in the Rosario fight is indication (I believe it is, a dog can't change its spots) the 1st time Pryor nails Camacho, he'd go into survival mode only. But unlike Rosario, Pryor would be relentless, esp if nothing is coming back to deter his aggression. In a 12rd fight, Pryor wins a unanimous dec. In a 15rd fight, Pryor possibly makes the referee stops the contest.
The Hawk would be relentless and only Camacho sturdy chin would stop there being a ko. Hawk at his best was near unbeatable at 140 lbs.
Can't see Pryor stopping Camacho personally. Guy had 88 fights up until the age of near 50 and was never stopped despite facing a helluva array of guys and some top notch fighters past prime. He had a really good chin and was extremely elusive and could survive if he had to. Anythings possible but i'd go strongly against it. The best chance Camacho would possibly have here is the version who schooled Ramirez pre Rosario. You would have him come in at 135 basically as he did vs Ramirez. He was incredibly elusive and had some serious moves and possessed supernatural speed. You'd still make naturally bigger and stronger Pryor a big favorite particularly given his superb stamina and relentlessness. Camacho would have to fight the absolutely perfect fight to have some sort of chance.
