Ali had stamina... he had the reach... and he has something tyson doesn't have... a jab... Ali had the ability to evade.
Tyson had the raw strenght and arguably faster hands than Ali... He was built like an Ox and could take punishment to the body... He was the one-punch wonder. He fought the whole fight just trying to land one good hook or upper cut... a blow in which claimed many victims.
Ali takes Tyson becuase he not only has a reach advantage which allows him to keep distance from Tysons attempts at his end-all blows... With stiff jabs Ali would wear him out. But also Tyson would have a height disadvantage that would allow Ali to come down on him and leave him covering his head. Ali knocks Tyson down a few times and ends it with a KO in the late 7th or 8th (like someone said).
