We don't need to wait and see, he's now fought Fury twice and Wilder couldn't do the job. He got outboxed badly in the first fight and outfought and stopped in the rematch. Fury is just a really bad match-up for Wilder stylistically due to his size, boxing ability, and versatility (as he showed on Saturday night). Wilder has the ultimate puncher's chance against anybody but not against Fury anymore as he has multiple answers to solve that big right hand. And even if it did land clean there's always a good chance that Fury recovers from it as he did both times in the first fight. Fury is just a very bad match-up for Wilder.
