How would old heavyweights do in the division if they were adjusted for size ?

People like dempsey or tyson even though short for today Would Dempsey really be that short ? He's taller than Chisora and Takam and about the same height as Rahman, Stiverne, Ortiz, Purrity and Brewster.

Without size adjustment i still think they would do well. People like dempsey or tyson even though short for today would be stylistic nightmare for people like wilder. Theyd break him and joshua down with body shots and power punches to the dome. There were some big ass dudes still back then. I think the footage from then just makes em look slow. But one thing is for sure they were alot tougher. Anyone that was a champ then would most likely be champion today. Id have anyone on your list beating joshua right now. Other than wilders power nobody looks “special” in the heavyweight division right now. Id give all those champs a good shot currently
