Remember folks, everyone at the time thought Liston was going to murder the young loudmouth Louisville Lip.
It was a foregone conclusion.
Clay was going down it was only a matter of time.
Doctors checking Clay before the fight were concerned that his heart rate was too high and his hyper behaviour was because he was in an unstable condition.
People saw this as fear, and in part they may have been right, but there was also an equal measure of excitement as well.

Yeah we all know what happened... a Legend was born, the greatest boxing legend ever known to humankind.
Poor old Sonny, if only he had known to keep his hands up.

Personally I don't think there was ever a fighter in any weight that compares to Ali in early 1967.
