I'd say this is pretty much a nightmare matchup for Pryor. He's open to be hit, charges in, how long until Jackson catches him with something? He hits a little harder than Arguello
Pryor could ill afford being "tapped" by Jackson like he was by so many others with those flash knockdowns he suffered periodically, or even when he didn't go down as with Arguello, who caught him cleanly many times..defensive lapses would be hazardous/fatal to Aaron's health vs Jackson.
