what was the greatest KO streak ever?

Tyson--Biggs, Holmes, Tubbs, Spinks, Bruno, Williams

Vitali--Johnson, Sanders, Williams, Peter, Gomez, Arreola

Foreman--Frazier, Roman, Norton

Hagler--Roldon, Hamsho , Hearns, Mugabi

 

Fitzsimmons between the Jeffries fights is pretty insane. Only Ruhlin took him past the 2nd round, and the fights with Dunkhorst, Sharkey and Ruhlin were scheduled for 25 rounds.

Perhaps Terry McGovern, with wins over:
Pedlar Palmer
Harry Forbes
George Dixon
Eddie Santry
Oscar Gardner

In a KO streak lasting 19 fights.

 

ALI RAYMI HAD 25 CONSECUTIVE KO`S, 21 IN THE 1ST ROUND.

 

Joe Louis had some impressive ones either side of the Godoy SD.

 

The records of Archie Moore or Jock McAvoy would yield answers to this.

 

Marvin Hagler ....12 title defenses ...11 knockouts....and he wasn’t really a “ puncher”

 

There was an amateur boxer from South Africa who lost his debut and went on a seventy odd KO streak and turned pro.

 

Seem to remember Nigel Benn having a good run of KOs in his early days.

 

Marciano 7/12/51-9/24/53
Rex Layne
Freddie Beshore
Joe Louis
Lee Savold
Gino Buonvino
Bernie Reynolds
Harry Matthews
Jersey Joe x2
Roland Lastarza
After that stretch one UD on Ezzard then back to KOs Ezz, Don C Archie

 

Wilfredo Gomez had quite a run of KOs So did Carlos Zarate. I agree with the earlier post naming Hagler. He fought at a time when the middleweight division was full of "tough guys." At the time, I really thought he'd have his hands full with the aggressive tactics of Scypion, Sibson, and Hamsho, but Hagler walked through all of them with a ton of room to spare.

After his clear loss to Marco Antonio Barrera, people mostly forgot about Naseem Hamed. But he was destroying top quality opponents one after another in his day. I'm sure there are plenty of others, but those are some guys that came immediately to mind.

 

Edwin Valero was 27 and 0 with 27 Knockouts, say what you Will about the man, but it’s very impressive non the less

 

Julian Jackson banging out Baek, Drayton, Graham and Norris among about 10 others.

 

Mike Tyson broke the then world record for first round KO`s when he scored his 21st first round KO at some point, Wilder went on to break that record.

 

And Duran had the exact same at lightweight - 12 defenses and 11 KOs. His first 10 were all by KO.
