In a heavyweight fight anything can happen. As long as he doesn't hold back, like Joshua did against Usyk, then Wilder still has a puncher's chance. Wilder is one dimensional so if he doesn't fight like the KO machine he's been his whole career then he will not make it past the early rounds.
He cannot and he should not fight the way he did in his last two fights against Fury, he has no chance to win if he'll just wait to drop his big bomb, that will not happen Fury is always moving always find a good angle, you know in boxing it's hard to hit a moving target, he must show something different like imposing himself, punching a lot and bobbing and weaving can help, he must show to Fury that he is a totally different fighter, few more days before we see the most anticipated fight of the year.
