i am a fan of boxing as well ,don't watch it much these days as i'm into mma and think boxing has had its day and mma is the way forward... Ali was a legend ,but he didn't have the explosive power of tyson..think if we are talking tyson 86-89 tyson would take it...although alot of tyson's opponents in that period looked defeated before they stepped in the ring..Ali wouldn't have that fear...it certainly would be the fight of the century
It would be the fight of a Life Time Karl

Henry Cooper could hit but cut very easy. Clay/Ali could take a hit even if it meant climbing off the canvas, the only thing then he would punish you verbally as well as physically

I remember in some of the footage I have some boxer would not respect the fact he had changed religions and name, so kept calloing him Cassius... so instead of Ali knocking him out which he could have done at anytime he wanted, he battered him none stop for the full 15 rounds

People have said Tyson was like Smokey Joe Fraizer but I really dont think so.... Smokey granted could hit but wasnt a mover... were as Tyson could hit and hard and move like lightening in his Great days.....
If Ali could prevoke Tyson and anger him (which I would not like to do

) then use the ropes like he was famous for maybe he could destroy him mentally?

If Tyson could catch Ali with his breath taking Power and Speed then that relentless killing instinct when his opponent was unsteady???
But although I am a Tyson Fan, I really believe in my heart of hearts that Ali would prevail... When you see the Foreman fight the size of him... you would have expected Ali to get killed, but he really knew that himself and so played his games... this in my honest opinion is what would have happened with The Great Iron Mike
