Who has the 5 best wins on their resume, any weightclass ?

I think Ali and Leonard are strong contenders for top honors (at least in the last 50 years) in this category for reasons already stated. But I'll add a few more -

Joe Louis has wins over the five fighters who held the title previous to him -
Carnera
Baer
Sharkey
Braddock
Schmeling

Even before he became a heavyweight, Evander Holyfield had wins over some notable fighters, titleholders, in the Cruiserweight division's short history -
Qawi
DeLeon
Ocasio

He also holds wins over 3 of the 4 lineal heavyweight champions previous to him -
Holmes
Tyson
Douglas
(Michael Spinks talked of coming back to challenge Holyfield if Evander beat Tyson in the originally scheduled 1991 fight)
As well as the 3 who held the lineal title after (or between his reigns, in Bowe's case) him -
Bowe
Moorer
Foreman

 

Barney Ross

Garcia x3
McLarnin x2
Petrolle x2
Canzoneri x2
Battalino x1

 

Ali
Foreman
Frazier
Liston
Patterson
Quarry
(Bonavena, Lyle, Shavers, Williams, Zorra, Norton exc)
Or Charles
Maxim
Walcott
Louis
Moore
Bivins

 

Holyfield’s resume is incredible.

 

Willie Meehan

Jack Dempsey
Sam Langford
Jeff Clark
Jack Dillon
Jim Johnson

 

Ali

Moore
Liston
Frazier
Foreman
Norton

+
Patterson
Chuvalo
Bonavena
Quarry
Lyle
Shavers

 

I’ll put this up with anyone:

Sandy Sadler

Willie Pep
Willie Pep
Willie Pep
Flash Elorde
Joe Brown

An interesting one on name value:

Hector Camacho

Roberto Duran
Ray Leonard
Ray Mancini
Edwin Rosario
Cornelius Boza-Edwards

 

While speaking of a George, there's one with a reasonable top 5 wins comparative to others.

Frazier x 2
Norton
Lyle
Moorer

Those top end wins compare favorably to a great many Heavyweight champions. Without even thinking he would have Marciano, Patterson, Liston, Holmes, Tyson and Holyfield covered. You could debate others too.

 

really got to be leonard, amazing quintet, and what makes it almost unbelievable is its 1/7th of his entire resume, including his score of fights as a contender.

few can claim that 1/7th of their resume is ATG.

Certainly noone can claim that 1/4th of their post prospect resume is ATG!

 

Jimmy Britt

In 22 fights he fought Kid Lavigne, Frank Erne, Young Corbett II, Joe Gans twice, Battling Nelson three times, Terry McGovern and Packey McFarland.

He has wins over Lavigne, Erne, Corbett, two wins over Nelson, and a fight with Gans, which if on the level he deserved to win.

 

FYC:

Floyd Mayweather
Canelo Alvarez
Manny Pacquaio
Oscar De La Hoya
Miguel Cotto
Shane Mosley
+
Juan Manuel Marquez
Ricky Hatton
Arturo Gatti
Genaro Hernandez
Diego Corrales
+
Zab Judah
Marcos Maidana (x2)
Jose Luis Castillo (x2)
Angel Manfredy
+
Conor McGregor (MMA champ), Tinshin Nasukawa (Kickboxing champ), The Big Show (2-time WWE and ECW heavyweight champ)

 

Geez! I'd forgotten about Zivic, great lineup there, man what a record guys like Zivic, Greb and Langford had!

 

Not even close to the greats

 

Nah.

 

I wouldn't say that. And, I don't know if you heard, but Floyd is a great, too.

Canelo will be a Hall of Famer. Pac will be. Marquez will be. Cotto. Oscar's in. Hatton's in. Gatti's in. Genaro is on the ballot. Mosley will be on the ballot. Castillo and Corrales have a shot based on their series.

Floyd's a first ballot Hall of Famer and he'll have about 10 Hall of Famers on his list of conquests ... with zero losses against any of them.
