It's not really his style to trade, he's a spoiler and will look to prevent such a fight taking place. Even if Fury is able to force his way inside and not be smothered and make it a rough fight he will be walking into Wlad's power and that is a risky strategy against a one punch KO artist like Wlad, especially with Fury's defensive lapses and chin.
No, Tyson's handspeed and how quickly he moves in would be the difference. Tyson pre-Berbick I think Wlad successfully clinches him but Tyson during his 87-89 run completely devastates Wlad.
Azzer85 says you're stupid for even questioning that, but I would say Wlad is a better big man than anyone Tyson ever beat so there's that. It always makes me roll my eyes when people bring up a fighters absolute worst nights as if that defines their career. Mike did a lot more in his career than just lost to Douglas, and same with Wlad
All Tysons are destined to fall down before Wlad. Wlad already beat the ¨white Tyson¨ Chagaev and the ¨french Tyson¨ Mormeck. Fury is next. This is destiny's way to tell us that Wlad would have beaten Iron Mike too after his next match, Wlad might rightfully adopt the nickname of ¨Tyson Killer¨ Klitschko
