I t's hard to think of a 140 lb. fighter would would ko Pryor when he was at his absolute peak. A few could hurt him but it was very hard to ko a prime Pryor.
i'll take mclarnin in this one, one of the harder hitters who could make 140 imo and a smart fighter too, not immensly skilled but pretty damn good and pryor was there to be hit.
Its possible if it had happened in 1980 and Duran decided to fight at 140 To me, it's hard to say because Duran never fought in that division.
Forget the 1980 relic that dropped Pryor, the prime '72-'74 version of Antonio Cervantes would keep him there.
Duran could do it SRL,Hearns not Floyd in fact Pryor was better than the Mosley that lost to Floyd or the Cotto that put the pressure on him,Floyd met no one that could fight like Pryor. Pryor was fluid and hit hard, had late power. Even Duran, Leonard and Hearns would feel the fire and have to outlast or spark Aaron
