All time would be Joe Louis. Its said that he could knock over a half-ton bale of hay with a 6 inch punch. For modern fighters Manny's counter punching is underrated by most. He is primarily a counter puncher. Feints to get them to attack then attacks. That is why Marquez has given him so many problems over the years. He feints Pacquiao's faints and then counters, see the KO.
:huh wait what? lol! Pac feinted in, Marquez didn't even react. He knew Pac was going to throw the jab right after and that's when Marquez slightly dipped to the left to avoid it then blasted Pac with that right hand.
I don't think we'll see something like that against a world class opponent again in our lifetime. Pure beauty. :good https://lh5.googleusercontent.com/-...%2520vs%2520Reggie%2520Johnson.gif?imgmax=640
:good **** looks like it's moving in fast motion but it's in real time. That's how freakishly fast Jones was.
Corrie Sanders. Look at both fights against the Klits. He lured them in, then caught them with that lightning fast left....
