The worst defeat for a world champion you've ever seen?

This would be unquestioned #1 if it was WBC, WBC or IBF

 

Lucian Bute to Froch

Errol Spence to Terrence Crawford

Outside of a flash knockdown Nonito Donaire at his peak was shutdown and dominated by Rigondeauz

high flying Vic Darchynian getting crushed by Nonito Donaire

Barrera coming off a career surge getting destroyed by Manny Pacquiao who was still sort of unknown to US audiences

Do we count Trinidad to Hopkins?

Jermaine Taylor getting crushed by Kelly Pavlik

 

Tyson with Tokio Douglas and Joshua with Ruiz.

 

Liston KO1 Patterson

One that I watched as it happened? Maybe Mayorga KOing Vernon Forrest right after Forrest got a big HBO contract and was coming off wins over Mosley.

Joppy being KOd by Trinidad was pretty bad

Montell Griffin being KOd in 1 by Jones Jr.

 

Martinez against Cotto.

From top to bottom it was an awful experience.

 

Was Pavlik champ when Hopkins beat the living hell out of him?

 

Toney vs Barkley. Not only did Toney win every round. I don't think he even hit Toney clean.

 

yes, I was going to list it but it wasn't a title fight though it was a champion getting embarrassed

 

I forgot about that one. I loved it.

 

Nunn vs Kalambay or Aj vs Ruiz in terms of embarrassment

 

Rahman-Lewis I comes to mind.

Nice clean KO, and poetic justice because of the unsportsmanlike way Lewis was taunting Rahman.

 

Leading up to Usyk v Fury I watched a bunch of significant heavyweight fights and this made the cut. Lewis backing away smiling with his hands low then BANG!!

Rahman fought with confidence and was not in awe of the moment. Each round Lewis played with his food and allowed Rahman to slowly climb into the fight and build confidence. The revenge KO was pretty brutal as well. Not too many recent series I can remember where each guy got a brutal KO

 

Frazier Foreman
Crawford Spence
Fury Wilder II
Tyson Spinks
Tyson Holmes
AJ Martin
Wilder Stiverne II
Garcia Haney
Wlad Haye
Liston Patterson

 

Berbick being bounced like a beach ball by Young Tyson was pretty one sided.

 

Livingstone Bramble vs Rosario
