Ben murphy had a real engine , no world beater but threw lots Gave theophane hell on short notice if I remember correctly
Margarito, Paul Williams, Ray Olivera, Emmanuel Augustus, Zaggers, Vince Phillips. Margarito holds the record for most punches thrown in a 12 round fight of 1675. Vince Phillips thew 237 punches in the 12 round alone against Ray Olivera.
Pound for pound, Vitali Klitschko. For someone his size to be throwing over a thousand punches in some fights is absolutely remarkable.
Margarito and Paul Williams immediately come to mind. Rahman (when in shape) has thrown an enormous amount of punches in a few fights. Also Calzaghe.
Joe Calzahe had a very high work rate. Combined with his superb conditioning, I'd say it was his greatest asset. Manny Pacquiao also had a tremendous work rate in his prime, often throwing over a 1000 punches per fight and he was such an awesome puncher. Its a real shame these guys have to get old.
I think Floyd would've beaten Margarito, I think he could box him after a few tough moments. I think he would've gone down in a hail of gunfire vs. Paul though. He wouldn't get stopped but paul doesnt stop throwing for anything. Margarito has times where he stops and starts
