We don't know who's going to win, so what's the point in discussing that? People are making assumptions based on the snippets of information through social media and what we've heard from his camp. If he was training with Dave Allen in Ben Davison's garage id be inclined to suggest he wasn't taking this seriously.
Fury is a legend after all he went through to come back and fight Wilder in his 3rd fight back. I think he stops Wilder late.
