Wilder could target the cut area near Fury's right eye and it could open up easily again, which could lead to the fight being stopped due to cuts ala TKO6. Wallin held back without going after the cut area, which allowed Fury to scrape though the fight, I doubt Wilder will do the same.
Wilder will likely be punching air for the majority of the fight, like he was last time. His best / only hope is via brutal KO.
