When I hear such things I almost instantly suspect that person of being Tyson worshiper. I guess those beliefs can be explained by the fact that Klitschkos are intelligent and calm rather than agressive. I have a theory that they deliberately postpone a KO just for the sake of pleasing the crowds, but the side effect is that it makes them weak in some people's eyes.
Anyway, this is total BS to me. But I never see the point of arguing over this with a Tyson worshiper.
