Good point. I'd also add that the vast majority of Louis' title challengers were white Americans, which significant white American Heavyweights are virtually extinct now. When was the last one? How many have there been over the last 50 years or so? They were all over The Ring's top 10 throughout the Louis era, but completely absent now. Not saying Chisora beats Louis, but I think Louis would be in for a little culture shock if he were able to time travel and visit one of the more recent Heavyweight eras.
