Which ATG heavyweight has the worst loss?

I am assuming we are considering the form of said heavyweight at the time of the fight.

Id say Tyson-Douglas or Wlad-Sanders.

Probably Wlad-Sanders.

 

Joshua is not an ATG heavyweight, although he may be considered as such in a few years, if he beats Usyk and Fury.

Worst losses: Lewis-McCall, Klitschko-Brewster, Klitschko-Puritty, Tyson-Douglas, and Ali-Berbick come to mind.

 

Wlad's loss to Fury

 

Lewis losing to Rahman has to be up there, too. McCall is a little better, and, much more durable than Rahman.

 

Ali to Spinks

 

I mean not worst opponent but most embarrassing defeat. Wlad lost every round. Now Fury is better than Wlad but to lose every single round. Lol. Even the rounds people like claim Wlad won he didn't. Clinching telegraphed mess of a fighter. Size bully got size bullied.

 

Wlad to Purrity
Foreman to Morrison and Jimmy Young
Holyfield to Moore/Toney probably his worst losses
Lewis loss to McCall was pretty bad since Lewis didn’t properly avenge the loss, fought a mental patient in the rematch

The two Liston fights for Patterson had to have been the most embarrassing at the time, the man got a lot of **** in the general public, Frank Sinatra even called him a bum.

 

First thing I thought was Joshua ATG? Not even in the top 100. Was very Lucy Ruiz showed up in terrible nick for rematch.

 

Ali's loss to Leon Spinks looks atrocious in hindsight. Worse than Tyson's to Douglas IMO

 

Dempsey lost by 1st round ko.

 

Hard to say: is getting sparked with one punch better or worse than taking a more prolonged beating? Are we just considering the ability of the opponent or do other factors come into play, such as how embarrassing the defeat is? AJ-Ruiz is the most humiliating I've seen but this is largely due to the aesthetics, with the prolonged battering by a B/C level opponent and quitjob compounding it.

 

Louis to Schmeling.
Ali to Spinks.
Tyson to Douglas.

 

A lot of them are pretty bad, but it just shows how in the heavyweight division anything can happen

 

Holyfield vs Vitor Belfort. The Florida Athletic Commission should fine itself for approving this farce.
