ali raymi, sven ottke and joe calzaghe all retired undefeated and had a collective 101 fights - 101. the BEST fighter any of them beat who were in their prime was mikkel kessler. let that sink in a minute. now go look at floyd's resume and you'll see what a truly undefeated resume looks like. being undefeated doesn't mean squat if you pad it full of cans.
