Prime Mike McCallum had trouble with Steve Collins, and he was a better fighter than Benn or Eubanks, don't think those examples are a given. Collins actually get's a bit underrated for fighting those guys at the end of their careers, he had done well in just as deep beforehand.

I think maybe Roy Jones vs Danny Green would have had a different outcome in 1995. How about Tyson vs Kevin McBride in 1988. Holyfield would have probably beaten Valuev a bit easier in 1993, that kind of thing?
