In boxing history? 9note I try to put the champion's name first, or in the case of a non title fight who was champion first)
I'm going with the Davey Moore / Roberto Duran bout. I can't say it was the worst with certainty but it looked like a horrific beating.
What about Calzaghe - Lacey? Of those listed Duran-Moore, a career ending beating, Hearns-Duran was a very swift execution.
Braxton-Saad II is up there, Also Ramirez-Boza When the all action Saad and Boza lost it they lost it totally and were completely shot. Boza smartly retired. Saad however was in denial and sadly carried on as an empty shell.
I picked Duran-Moore from the list, and would nominate Roy Jones-Richard Hall and Simon Brown-Jorge Vaca
