How Far Does Bruno Go Against Sonny Liston?

I agree with you. However, we know that people who sparred with him said he was the hardest puncher they ever faced. Foreman said Liston hit him harder than anyone else. I think Liston's power was comparable to Tyson and almost certainly greater than Witherspoon.

Once Liston lands on Bruno, i don't see him surviving.

 

Similar things were said about Marciano, though, and the two-tiered judgement stands.

 

Liston was a bit more methodical than Tyson, and he had a certain cautiousness to him at times, so it might take longer. But then again, Liston had a much better jab than Tyson. Yet, Bruno had height, reach, really heavy blows, and just a bit of footwork, and was good enough to keep Lennox Lewis and Witherspoon off him for several rounds. I lean towards Liston by late rounds KO, perhaps KO8.

 

Liston had a better jab than Mike and was a heavier puncher. That said, he wasn't particularly fast.

They put on a very good show, Bruno getting off some significant shots. But Frank couldn't deal with the jab and power past 4 rounds imo.
