Great call regarding floyd-inga. They KO each other so quickly that most has forgotten what a great and significant matches they were. Another that usually slip under the radar were Harding Andries, a true barn burner.
If Zale-Graziano counts, and I don't believe we have footage of two of those fights, then Pep-Saddler and Charles-Walcott deserves to be in there. Did anyone say Chacon-Limon? Gonzalez-Carbajal, Duran-DeJesus, Griffith-Paret, Ross-McLarnin.
