Wilder took Furay's place in the fight with Ngannou. What would happen? Take whichever version of Wilder you want for this fight. It would be nice if you could write which version it is. 10 rounds.
Unlike Fury, Wilder would take the fight seriously and actually train for it. Keep on the outside and snipe with his jab and don't let Ngannou get in close, and he cruises to an easy UD. If he starts headhunting for the KO, he opens himself up for getting a smashing overhand from Ngannou which would put him down. Wilder wins if he fights smart and sticks to the gameplan.
