Fighters who faced the highest number of high quality opponents

Ossie Ocasio fought:

Lennox Lewis
Bruce Seldon
Tyrell Biggs
Ray Mercer
Pierre Coetzer X2
Evander Holyfield
Dwight Muhammad Qawi
Alex Garcia
Carl Williams
Mike “The Bounty” Hunter
John Odhiambho
Randy Stephens
Eddie Taylor
John L Gardner
Michael Dokes X2
Larry Holmes
Jimmy Young X2

(The Qawi-Lewis fights at the top of the list were consecutive, including both Coetzer fights — that’s eight pretty danged tough bouts in a row.)

 

In the modern era I would say Kevin Johnson, he fought Vitali Klitschko, Tyson Fury, Anthony Joshua, Kubrat Pulev, Andy Ruiz Jr., Daniel Dubois, Filip Hrgovic, Martin Bakole, Agit Kabayel and Dereck Chisora.

 

Maxie Rosenbloom, Jack Britton, Ted Kid Lewis

 

To follow up with my comment, it appears that McLarnin fought 42 guys in the top-10 out of 69 total bouts, meaning: he spent about 61% of his career against ranked opponents.

 

Lennox has a great resume.

 

In modern times Manny Pacquiao gotta be up there

 

Bobby Chacon fought:

Rafael Limon X4
Cornelius Boza-Edwards X2
Ruben Oliveras X2
Arturo Leon X2
Danny Lopez
Ran Mancini
Arturo Frias
Alexis Arguello
Chucho Castillo
Arturo Pineda
Shig Fukuyama

Schoolboy didn’t skip many classes.

 

Muhmmad Ali all due respect ain’t in the convo… Manuel Medina is a more recent fighter (sort of) he fought everybody.
