Arguello late stoppage or ud 15. He had a very good right, and he could use it as a lead effectively (what he KO'd Rooney with). He could cut people up pretty good, and he was also a very good technician who could slug it out (like he did with Pryor in the rematch). He was able to drop a coked up Pryor, so I have no doubt that if he landed flush enough, Pacquiao would fall as well.
