1973 Foreman vs 1959-62 Liston

Liston of the williams 1 to patterson 1 fights challenges george for his newly won HW championship instead of norton.
I got Liston maybe even in dominant fashion within 6 brutal rounds. Both very strong and hard punching but Liston was technically FAR superior. foreman had no way of avoiding the jab or the straight right. Foreman was so strong that he was used to just blasting his opponents out with haymakers and they wouldnt be able to stop him. I think Liston beats him to the punch over and over, survives a few wild swings and drops him in round 3, again in round 5 and finishes him in 6.
There was also the psychological component of a real genuine tough guy vs someone who just wanted to be one because he didnt have the self esteem yet to find out who he was. IMO when you have a fake or otherwise not genuine image, it tends to crack under extreme pressure

 

George CERTAINLY has a punchers chance, and could do all kinds of damage early

 

You don't know what you're talking about. Duran quit as well. In a similar situation as Liston vs ali. In this fight it would be foreman's resolve that would be tested because he would already be at a disadvantage stylistically. Liston fought with a broken jaw, KO'd williams with a broken nose. I'm not talking about quitting because of frustration. I'm talking about mental capitulation in a punishing brutal fight. You have to really love fighting and really be who you want people to think you are, to win a fight like that

 

You have to consider the technical and stylistic aspect. Listons reach was 5 inches longer and his punches were straighter.

 

I was impressed with his punch resistance vs Cleveland Williams and in contrast to george he covere up smartly when hurt/under fire. George was too strong for his own good, he had a lot of bad habits because of it

 

You can't make generalizations like that. Not if you know anything about psychology
Plenty of fighters used to show tons of heart but later eventually just couldnt take it anymore and quit. Plenty of fighters have quit but eventually later in their careers found the courage within. You don't know what happened in the fighters' personal lives. Fighters are not robots. Only if a fighter has a long history of quitting in winnable fights can you really say that guy doesn't have "it".
If a fighter has an impeccable mindset every single time he's either dumb as a rock or he's in a way insane/has an abnormal psychological make up(as in abnormal even for a fighter, fighters are generally mentally stronger than the average joe but still).
