I'm sure this has been done to death before I joined this site. Who improved the most after their fight and how would a rematch have panned out?
RJJ improved more after they fought but BHOP lasted longer because he was able to use his superior boxing technique later in his career whereas Jones relied on his sick ass ability.
People discredit Roy's victory over Hopkins because Hopkins was "green" but tend to forget that Roy improved a good deal also since then.
