My guess is no, he could beat up freshly deceased corpses for all his career if he can have a say. Let's not forget, he fought even an internet troll 70 lbs lighter, that's all you need to know about this guy. Had Charlie Z demanded the fight in 1 week I know Wilder would have sell tickets for it too
Calzaghe did it for 95% of his career, while Wilder is only at the 40% mark of his career. Let's be fair.
