Wilder tried to survive but he just doesn't have anything left. Fury was clearly the more technical and smarter fighter and he showed that in both fights.
After the first knock down he was never the same fighter and Tyson Fury completely dominated the fight and fulfilled what he was preaching before the fight that we would knock out Wilder which i was having my doubts as he was never a knock out fighter but he came up with a different fighting approach than his first fight and Wilder did not have an answer to it. Wilder have a rematch clause and whether he will take that is to be seen and now we might see the Anthony Joshua and Tyson Fury fight which will be another huge fight.
I also have the same doubts that the can knock out the Wilder.
But as soon as Wilder hits the canvass, the complexion of the fight changes, Tyson Fury more confident but cautious with Wilder's right. But Deontay was disoriented and it seems he surrendered already as Fury completely dominated the fight.
For me no need for a trilogy, Fury might go heavy again and the same results, Wilder getting knock out maybe under 7 rounds.
