Not DDD, he can`t evade jabs and Wlad was all about the 1-2, Dubois shorter reach hurt him v Joyce and would hurt him v Wlad`s 82 inch jab, it would be like Haye v Wlad.
I think that relying on your chin for defence against a guy like AJ is plain stupidity. Even if AJ gasses and Joyce manages to KO him mid rounds it will be a hollow victory because he's going to look like an extra for a horror movie.
