Re: would the rope of dope worked against...
Agree that he didn't need it in 1964 and if he used it, it probably would not have been as effective against Liston.
Also, in 1964, Ali's capacity for absorbing punishment was largely unknown and untested. Had he gone to the ropes and started taking shots, it may have been interpreted as Ali being hurt and defenseless. The referee may have stopped the fight before the strategy had a chance to work.
