I've answered this before & caught heat for it, so if I find my post in a very similar thread from about 3 months ago I'll post it in. But as it's late over here, I'll just summarize with this. I think Pacquiao stops him in 5-6. I'm of the view that Aaron Pryor is one of the most exciting fighters of all time, but also one of the most overrated. Credit for the Arguello wins, but Pacquiao is a little better imo & also has for my money a much better chin. Great fight while it lasts, but Pacquiao stops him after a short war. Okay I'll prepare to get flayed
