That running shoulder faceplant is nothing like the world's strongest slam lol He could be a future replacement for Henry. Henry hasn't got long left, from his own admission, so they will probably just wait until Henry goes before they call him up.
About the World strongest man comment, his gimmick is of a powerlifter. He has pictures of barbells on his entrance video and static pictures on the side screens. He comes out slapping his chest with chalk all over his hands (commonly used to aid with grip for heavy weights). When he comes out Regal says "there is not a man stronger in the world" but must have made a mistake because when Big E enters the ring, Regal then says "I truly believe he's one of the strongest men in the world"
