I remembered today that Arum called Pavlik the hardest punching middleweight he'd ever seen.
I wanted to see whether anyone agrees with him. Obviously Pavlik's a hard puncher, but the hardest at 160 ever? I actually think McClellan had more brute power, I also like Hearns's pop more. Pavlik's a crude puncher, he doesn't really get a great deal of leverage much of the time I've notice but his power seems to come from his shoulder, it's quite unique. He times the uppercut very well.
I agree with the other posters that Pavlik is an accumulation puncher, he will chip away at you consistently.
Earl is correct AA hits much harder than Pavlik imo.
Pavlik might have more physical strength but i believe as you said that G-Man and Hearns had more destructive power because of better leverage, technique and speed.
With that said Kelly Pavlik is still a great puncher.
