The only thing that ever so slightens (is that a word :hihi:) the Pettis kick was Henderson has a solid chin and managed to recover to grab a leg. Hypothetically, had that kick landed, where would it rank in the list of all-time KOs?
Does it exceed Smith/Sell? Arona/Ramage? Wand/Rampage? Something else I forgot off the top of my head from the thousands of options?
