In terms of the quality of opponent...

Some of the old ones are tricky because of weights of the fighters. So many were missed off. Similarly any tricky decisions have been left off too.

Schmeling WKO 12 Louis
Frazier W 15 Ali

Greb W 15 Tunney
Greb W 15 Loughran
Charles WKO 8 Moore
Moore WTKO 14 Johnson

Papke WTKO 12 Ketchel
Robinson WTKO 13 LaMotta

Armstrong W 15 Ross
Robinson W 15 Gavilan
Duran W 15 Ray Leonard
Ray Leonard WTKO 14 Hearns

Canzoneri WKO 2 Chocolate
McLarnin-Ross-Canzoneri (all over one another)
Armstrong W15 Ross

Saddler WKO 4 Pep
Pep W 15 Saddler
Driscoll W 10 Attell
Sanchez WTKO 15 Nelson

Harada W 15 Jofre

I might have Ali's 8th round KO of Foreman as the HW division's best. And perhaps Robinson's one punch KO of Fullmer as the MW's.

Very good list!
