Can any boxer in history face Oscar Dela Hoya's opposition and retire undefeated?

TBE (not The Best Ever) can with ease... I think the 4 horsemen of 80s as well...

I think the issue with the 4 Kings is weight class. I mean I am sure Hagler could beat everyone on the list, if he is allowed to come into the fight as a MW, but a fair number of those fights took place at LW & below. I just cant see Hagler or Hearns being able to boil down that much and being able to walk to the ring.

Thats what makes this question tough. It has to be someone who could feasibly fight at 130 during their career, and still beat a full fledged B-Hop at some point in their career.

Excluding half of the weight classes, 130, 135 and 140.

In that case...Sam Langford and Floyd Mayweather Jr.
