Saw the video a few days ago, though I enjoy it, I don't agree with the list. but there close. 1 Marciano Walcott, 2 Next I put Charles 1 here, that was a 15 round battle, perhaps shows Marciano's best punch output. Charles put on a show there. I have a ideal of how the fight went down, I made a trend on the subject years ago, having listing to the radio broadcast and getting a ideal of what rounds went to who, Charles wins the first 4 or so rounds. Around round 5 Marciano turns the tide, and pretty much controls the rest of the fight from 6-15. Though I wish I can see the full fight, listening to the broadcast was the next best thing. In the final rounds, Marciano put on a high punch output that was rarely seen. 3, I put The Moore fight. Outside of the flash knockdown, I think it was a pretty one sided match. But as you said, it was impressive to see Marciano's punch output and Moore taking it. Moore had lots of heart. 4 Charles 2, Marciano though controlling the fight, does over come a split nose to take Charles out in round 8. As for 5, Perhaps the Louis fight. Though the Rex Layne fight put Marciano in the top ten I believe. Either one would be a 5 for me.
