Boxing can make the best case compared to other sports.......

.....in which previous participants as a whole from prior eras would dominate it's current era, by the widest margin.

I don't quite see that in regards to other sports.

The UNLV men's hoops team from 90-92 could still hang 20+ years later. They were that good

Yeah and I'm sure the Riddick Bowe of 1992 could still hang very well with Wladimir Klitschko as well. There can be made a decent case that Bowe might win too! But prior to the 90's, we are struggling to find examples of guys who could hang in current boxing and also in other sports too.

You will struggle to find a single tangible record at the Olympics for instance, no matter whether the event is based on athleticism, skill, strength or a combination thereof.
