...pads don't hit you back

I think to answer this question we really have to answer the question of "What's the best KO each fighter has?" and not meaning over the best opponent or anything but the most violent KO each fighter has...I think Pacquiao-Hatton and Abraham-Taylor rate at the top.

I'm not sure Vitali even has a big 1 punch KO recently...he hasn't really sat on his punches since his return.

Wlad's big KO's are: Austin, I don't care who it was that got clocked by those hooks they were done; Brock, anytime you face plant someone into the canvas you've done a good job.

Haye's best might be Macca or maybe Bonin was his best show of power..I don't know
