How competitive would Aaron Pryor vs Duran be?

Duran stops Pryor based on his boxing ability and his superior defense. Arguello was timing Aaron with clean right hands had those been Duran's right hands Pryor is going down eventually.
We know ETM didn't have Duran's speed or defense. Roberto was able to hurt bigger men as he moved up including Ray Leonard, Davey Moore, Pipino even Barkley at 160. Aaron at 5-6 is gonna have to survive Duran being in his range. Pryor cant be safe on the outside at any point.

Also Pryor acted crazy, Duran was crazy.

 

Aaron was more than that. He was a champion but I agree with your result.

 

The biggest deficit would be Duran's defense as well and boxing ability.
