IMHO Iron Mike had a style that was tailor made to beat Ali prime vs. prime. On the flip side I imagine that prime Liston, Foreman, Marciano, Tua, and Ibeabuchi had the best styles and abilities to beat prime Tyson. Tyson seemed like the kind of fighter that had to be beaten by KO and I don't think that Ali had the power to do that against one of the best punch slipping heavyweights of all time. A fighter with a granite chin and tons of power that could catch Mike with the perfect punch would be the perfect match against him. I got a lot of love for both Ali and Tyson because they brought so much excitement and attention to the sport of boxing.
