Greatest victories ever?

Holyfield defeating Tyson (1st fight) has to be on there and I'd suggest Nigel Benn over Gerald McClellan.

Others to consider :

Bernard Hopkins defeating Felix Trinidad
Marco Antonio Barrera defeating Naseem Hamed

Also a little criticism of your list - Toney's win over Holyfield should not be on there while it was a great performance by JT Holyfield was almost 10 years past his prime by then and I'd also put a question mark over RJJ's win over Toney, again on paper a great win but JT was badly weight drained and looked a shell of himself.

 

Schmeling's victory over Louis is the best victory in heavyweight history.

 

Douglas Tyson neither guy was considered prime so it's fair

Sanchez Gomez

 

Imo:

Pep beating Saddler
LaMotta beating SRR
Louis beating Schmeling
Frazier beating Ali
Ali beating Foreman
Marciano beating Charles (second fight)
Marciano beating Walcott (first fight)
Sullivan beating Kilrain
Duran beating Leonard
Dempsey beating Willard
Dempsey beating Firpo
Dempsey beating Fulton
Dempsey beating Sharkey
Greb beating Tunney
Walcott beating Charles (third fight)
Braddock beating Baer
Foreman beating Moorer
Douglas beating Tyson

Sorry for so many

 

Joe Downey vs Soldier Bartfield.
Louie Brown vs One Round Hogan.
Joe Louis vs Primo Carnera

 

Ali was in far better shape when he met Foremen than the shape he was in for the Frazier fight. Bowe was out of shape against Holy. Toney couldn`t cut the ring of vs Roy, Griffin fought much better against RJ and threw far more counters as did a 39 year old McCallum during the early rounds of his bout vs Jones. Ruiz was awful and wouldn`t throw any leads, he just stood there waiting. Holyfield was too old vs Toney. Canelo fought the wrong fight vs Floyd during the first half of their bout and is twice the fighter he was back then now.

 

Carnera was very easy to beat.

 

Tyson was awful vs Douglas. Foreman was being beat before he caught the weak chinned Moorer. Here`s a thing Douglas may have been able to beat Moorer and the Foreman may have beaten Mike as he was in Tokyo!

 

Tyson was past his prime vs Holy, McClelan had no defense at all vs Benn and Naz was falling off balance after he punched and simply got exposed by one of the fastest counter punchers in history.

 

It was real life David vs Goliath.

The 5ft 5 inch, 180 pound Joe Louis slayed the 7ft 4, 380 pound giant. It goes down as not only the greatest victory in boxing history, but sporting history.

 

I'm probably going to regret this but I'll respond to you anyway :

Tyson had won two world titles in impressive fashion prior to beating Holyfield, was he past his best ?? Yes but so was Holyfield who has just been stopped by Bowe and lost to Moorer. EH was a huge underdog and expected to be stopped inside 3 rounds instead he stood his ground and destroyed Tyson's aura forever.

McClellan was a devastating and feared puncher, expected to be an ATG in the making most people believed, a huge favourite against the supposedly washed up Nigel Benn.

Naseem Hamed was undefeated, had won every world title there was at Featherweight and had effectively cleaned out the division, again Barrera was the underdog and in his first fight at FW dominated the lineal champ.
