I've
always been a fan of heavy handed - one punch KO power fighters.
A few that come to mind are...
Julian Jackson knocking seven bells out of Terry Norris

Terry Norris knocking seven bells out of John Mugabi

Gerald McClellan knocking seven bells out of Julian Jackson
I think i'm right in saying that after McClellan destroyed Julian Jackson - his next fight was against Nigel Benn.
I remeber saying to the lads at work that Benn was going to get KTFO inside 2 rounds (nearly happened too!!!)
If the time is right - there's nothing like 2 great heavyweights going toe to toe. The Bowe / Holyfield fights were great entertainment.
Oddly enough, some of the best KO's i have seen in heavyweights involve Tommy Morrison
Getting mullered by Ray Mercer & getting chinned by Michael Bentt
