Vitali thought if he named his fist after metal it would be just as potent as Wlad's, pretty sad really. I think Fury has a bit more power, actually. Reason is he's one-punched a few actual contenders. Also he stopped Chisora on attrition fighting off the backfoot (and southpaw) and Vitali couldn't do it. Vitali looks like he's really trying to hurt people with the arm punches but it's just slow death really. When Fury is boxing defensively he's obviously not throwing his hardest and so it makes sense the punches aren't huge. Fury would 'clown' Vitali as the Muricans say. Wlad was way more fluid and had no idea how to deal with Fury. Vitali would be clueless trying to hit a moving target and who wasn't 6'1.
