Another shout out for Jefferson vs. Harris - that punch was sick. Also the shot Ike Ibeabuchi landed on Chris Byrd was amazing.
Both all time great KOs but when you look at the level of the opponents faced there is no comparison. Duran is an all time great with an all time great chin. Graham is a very good fighter with an average chin at best. Because of that I rate Hearn's KO higher. Hearns is in the elite club of punchers who knocked out a genuine all time great fighter with a great chin.
Ruddock v Dokes comes to mind Hearns v Duran SRR V Gene Fulmer Hearns v Cuevas Ali v Liston 11......Kidding Tyson v Carl Williams The list is endless
Totally forgot about Ruddock/Dokes. An absolutely brutal, sickening KO. A full on "The Smash" against a wide open Dokes. Apparently Dokes was out for several minutes on the canvas. Definitely Top 10.
Honorable mention is the last left hook Trinidad landed on Campas before the ref stepped in to stop the fight, Campas head looked like it was going to fly out the ring.
