He was bigger actually and clearly so. It doesn't matter though (at least shouldn't, for some size is everything).
I like Max as a fighter, but he's from a vastly different era. Wlad in his more mature prime is too powerful, he's bigger, stronger and a better athlete imo and he'd be smart enough to know when to use his size and clinch if needed. Schmeling might make it somewhat interesting for a while, but WK likely chops Max down in seven or eight rounds.
Schmeling was ten times the boxer Klitschko was, and an ATG puncher that beat the great Joe Louis. Who the hell did Klitschko ever beat?Tony Peters? lol Max would easily get past the stiff robot, and one punch on that china chin and that's all she wrote. Yeah Wlad might be a giant but he was no better than Carnera, worse actually since he couldn't take a punch and panicked when put under pressure. Bert Sugar said it best, Wlad was a bum who beat bums lol. He'd get crushed by anyone that hit him back, and that's old Maxie. How did I do?
