Fighters more famous for fights they lost rather than won

Ruddock for the Tyson fights.
Spinks for Tyson
Basically every single fighter who lost to Tyson.

 

Golota Vs. Bowe 1 and 2

 

Michael Moorer against against George Foreman
Sonny Liston against Muhammad Ali

 

Mugabi for the obvious one. His best actual win is probably James Green.

 

John C Heenan

 

Wepner-Ali

 

This is a bit cruel, potentially, but are Roberto Duran's amazing efforts against Leonard and Barkley more famous/infamous than his No Mas loss?!?!?!!?!!!?

This is a scorching red hot question. No Mas was enormous. There's bound to be plenty of knee jerk outraged reactions of NO!!!!!!!! Is that, however, the correct answer?

I'm inclined to say No Mas might be at the top, as unfair as that feels given he had an outrageously great career.

 

Better to be known for No Mas than his dreadful performance against Kirkland Laing.

 

Meldrick Taylor against Julio Cesar Chavez in their first fight.

 

Dren Zidruniak.

 

Andrew Golota

 

I always thought that Jose Legra was the poster boy for this.

Some others:
Ayub Kalule
Vassiliy Jirov
Antonio Cervantes
Ken Buchanan, arguably

 

Jose Luis Castillo

-Losing to the top fighter of his era by controversial decision

-Losing in the best fight of his era (maybe any era). That had some controversy too with the extra time from the mouthpiece

 

Marvis Frazier twice (Tyson and Holmes), although I don't think Marvis is known as much because of the loss, as the son of Joe Frazier.
