Who is Ezzard Charles knocking out in this clip? The film is silent. It's from Argentina television and is tagged 1930, but it clearly isn't. This content is protected Based on the referee ... who appears to be Tony Wardorf (based on his hair and clothes from this photo of Charles-Barone http://boxrec.com/media/index.php?title=Fight:17164 ... boxrec says Wardorf also reffed Charles-Walter Hafer in 1948 (which ended in KO). Is this Ezzard Charles-Walter Hafer? Or is this Ezzard Charles vs someone in the 1950s ... like Joe Kahut? Let me know what you think. On top of it, it appears the guy took a dive. He does kind of the fake fall and starts rolling around when the referee gets to 10.
Bernie Reynolds. And certainly no dive. Charles near spun his head backward with that left hook, then the right sends him falling the other direction, and he takes a nasty fall on his face.
If for whatever reason, Charles threw his hook from the outside after Foster launched his. Charles was too great at feinting and positioning to get caught by Foster, quicker on the trigger too. This isn't Mike Quarry or a 39 year old Dick Tiger we are talking about here. This is a man who out boxed the best technicians of his day and had the power and durability to mix it up with 180-210 pound heavyweights.
That's a different scenario to what you described. Walcott and Foster are two completely different animals. Not to mention it was a perfect storm, after losing two fights, Walcott finally got Charles to perfectly bite on one of his many tricky feints in a pretty unnecessary third meeting. Not something I would bank on being repeatable. In fact it wasn't, Charles was said to have out boxed Walcott in their 4th controversial fight. I would say Walcott would KO Foster too and likely wouldn't need two fights to do it. Foster got outboxed and staggered by a declined Zora Folley.
