Probably, as Fury was deemed unfit to fight. I definitely wouldn't bet on Fury in that rematch under the circumstances. But I still think it would have been interesting to see. Because if Fury just went crazy in there and started dogfighting, it could throw Wlad right off and who knows. Fury is also very determined once he gets into a fight, so he could probably push pretty deep despite not being properly fit. It's not out of the question Fury goes in with a do or die mentality, brawls Wlad and ends up catching him or countering him etc., even wearing him out and outlasting him.
Yes. Wlad figured it out in the 12th round. In the rematch he would have gone straight at him and eventually caught him under 8 rounds.
I'll give Fury his due: face to face he's a real pain to deal with. Two minutes in and Wlad was feeling like a dumbell.
Since the if in this scenario is....if Fury was fit to fight, then my answer is no, he would not have beaten a fit Fury in a re-match, I'd give him little chance at least
