And Shelly Finkel stated after the Stivern fight that Wilder was just a baby and not ready to Wlad after 30+ fights so there was no chance to Unify.
the answer is Wilder got his ass whooped so bad in camp that they didn't think he stood a chance so Finkel went on record taht the fight was not going to happen.
The WBC basically blocked Wlad from fighting for their crappy belt once Vitali had vacated. They wanted the champion to be in-house. As for who wins that's an absolute no-brainer. Even dinovelvet would be hard pressed to give Stiverne a chance.
