I was in Guaymas, Sonora Bay in Mexico when the fight took place. Club Med had a location there back then. Tyson was a true knockout artist. Muhammad Ali was a tactician that may have been able to bait/lure Tyson into tiring himself so Ali could make his move.

beverley, He had a brother who was a heavy weight fighter as well. Muhammad Ali knocked him out. the Spinks Bros ! ! !

Unreal Neil.
Centenarian, Not as good as Mohammed Ali.

I am not so sure about this. South Africa's Gerrie Coetzee knocked him out in the 1st round.
