Between 1970-1977 we had like 4 different versions of Ali... While 1970-1974 versions of Ali could defeat prime Tyson, I don't think other versions could.
Too many versions of Ali in that time period, i could just pick the Ali who fought Shavers and send him straight down to the deepest pit of hell against Mike Tyson, or pick the one who systematically destroyed Jimmy Ellis and favour him to outhustle Kid Dynamite
