Maxie Rosenbloom's insane record against top 10 ranked opposition

To which fighter does the resume with the most depth in Boxing history belong to, win or lose ? Does it belong to P4P greats like Ray Robinson, Henry Armstrong, Archie Moore, or the unprecedented Sam Langford and Harry Greb ? Perhaps maybe someone like Fritzie Zivic ?

It is in fact none of them, the real answer is Maxie Rosenbloom:
