Really is not even close? At the time nobody was giving Ali much of a chance... And, Liston was looked as an unbeatable beast...

Liston was an 8-1 favorite and Tyson was a 40-1 favorite.

Not even close. Douglas-Tyson was one of the biggest upsets, if not the biggest ever. Douglas was a 40-1 underdog.

Tyson Douglas was the biggest upset in boxing history.

All you need to do is look at what happened to Ali and Douglas after their fights with Liston and Tyson respectively.

In hindsight, maybe Ali's victory over Liston wasn't an upset after all. Maybe he would have beaten Liston at any time, any weight, and at any circumstance. He became an all time great, after all. Douglas after Tyson, however, was a nobody. It was a one in-a-million chance.

Douglas over Tyson by a long mile.

I'd say Leon Spinks beating Ali, and his brother beating Holmes twice were slightly bigger shocks than Ali beating Liston.. But Douglas beating Tyson???
Not one mortal living, normal human being gave Douglas a hope in bloody hell..
It had already been established by then, that in order to stand a good chance of beating Tyson, you had to take him into the later rounds and Buster had a reputation for gassing at this stage in fights, so on paper this fight was an accident waiting to happen...... Massive, massive, massive shock!

Buster over Tyson.
