I always had a prime Tyson beating a prime Ali simply cause a prime Ali relied on physical ability like Roy Jones Jr. I have a experience Ali beating and a prime Tyson cause he would of relied on wits instead of reflex unlike Roy Jones Ali had a back up plan once his reflex slowed.

So a prime Ali would of relied on pulling back from Tyson punches and Tyson would of caught up to Ali in the later rounds (or maybe in the beginning). An Ali with some experience would of done better cause he would of used his mind.

And we all know their is no such thing as an experience Tyson cause a prime Tyson died in his prime.

For the record when Ali fought Patterson, Patterson was being trained by Cus and I believe that makes a huge difference.
