Perhaps he can come in at 400 pounds. That way, he can be the fattest person that Wlad has beaten. At least he will achieve something.
Doesn't matter, as long as he is at least 200 lbs so the fight may continue and Wlad can finally put this bigmouth in his place. But I guess the question is about what gives him the best possible chance of an upset... I guess as heavy as he can get without getting out of shape and losing too much speed. He has to KO Wlad, that's his only chance so he has to get as much weight behind his punches as possible. He can't win on points because his punchoutput is too low and Wlad wil jab him to oblivion.
LOLOLOLOLOLOL!!!! Why is everyone wondering about Hayes weight against Wlad. :huh He's gonna get trashed. Hell, he might even go flying if he comes in really light.
