Credit for what? Getting his fighter KTFO? From the very early rounds Hunter was heard to say in the corner, "he telegraphs everything." What did Virgil Hunter do to prevent his fighter from getting hit full throttle by right hand mus**** shots to the side of his fighters body. How does a fighter combat speed? Let me tell you novice, you go hard to the body and bring his energy level and guard down. Canelo worked that plan to perfection. Canelo was getting closer and closer to range with each passing minute, due to the result of Khan's legs and guard starting to wilt from that body assault. Anybody that had Khan winning more than 3 rounds doesn't count body shots when scoring a fight. You take away Canelo's body assault and Khan was up 5 rounds to zero. Class dismissed!
Khan was wincing everytime Canelo was landing that right hand hook to the body. Khan was wincing and wilting from the body attack which is why Hunter must have told him to take a round off, to recover from those brutal right hand side shots Canelo was propinating on him.
