Rate these heavyweights in terms of the opposition that they beat.

Saying Lennox Lewis beat Tyson doesn't count
Saying Marciano beat Walcott Charles or Moore doesn't count
...and so on

Lennox Lewis
George Foreman
Muhammad Ali
Jack Dempsey
Sonny Liston
Joe Frazier
Vital Klitchko
Wladimir Klitchko
Mike Tyson
Larry Holmes
Jack Johnson
Rocky Marciano

Damn this is tough im gonna have to think about this one, but obviously Muhammad Ali is at the top and Klitschko bros and Marciano are at the bottom. Infact no disrespect to Vitali Klitschko but i think his resume is shite in all honesty.
