I don't mind you thinking he'd beat any HW pre Ali, that's your opinion. But to say he'd destroy ever one of them, when you don't have that much knowledge of the era, isn't gonna get much credibility.
Fair point. I do not know the histories, styles, strengths and weaknesses of every HW champion pre-Ali. I do know that science has increased the size, strength, speed and power of the human body. And this fact alone is enough to assume a very talented and extreme form of a human being (eg Tyson) could beat guys from long long ago.
