By this century you mean since 2000 right cause the link has Ray Robinson listed. If its from the past 18 years maybe Roman Gonzalez he was the first name that came to mind.
His offense is very predictable and he puts all his weight on his lead leg, meaning you can read his shots as he`s about to throw them, he`ll have a hard time hitting Wilder, because of the treat of the right and it will all be at long range, plus Wilder has fast reactions.
