Listen Fenster it was not one punch that rocked Pavlik he got hit with like 40 something power punchs that round and still made it. To me that means the guy has to have chin or he would of been koed. Taylor has good power but look at the fighters he faced in his defenses they were great defensive fighters that are hard to ko i mean come on. To me it was more of a denfense issue then chin issue if you ask me but just a thought.
