Out of all the threads you could make, you posted up this? Why? atsch You haven't even spelt the fighters names right.
It's a legitimate question, if somewhat disrespectfully phrased. Which knockout was the most devastating to Khan at the moment it happened? Clearly last night's. His central nervous system was all but shut down. As to which was most deleterious to his career and health, probably Garcia. He took a lot of heavy punches to the head while concussed over a couple of minutes and his pride kept him coming for more unnecessary shots that he will hopefully not pay for in future.
