Pac was actually not an A1 puncher. He was a good puncher, but people overestimate his power. The knockdowns and knockouts he got during his asscent were more due to speed and angles than power. The evidence is right there in your face. What does Clottey, Margarito, Mosley, Marquez, Bradley, Rios, Algeri, Vargas, and Broner all have in common? What about Jeff Horn? Had the guy dizzy and still couldn't put him down. Pac had a few big time knockouts, but he was never some huge puncher - at least after becoming known known.
