No, I disagree with that. Obviously he is proud of being undefeated since being a teenager and rightly so. I see nothing arrogant in being proud of your accomplishments. He knows his own self worth and that is not neccessarily a negative character trait.

I quite like how he comes across as a person and am of course a fan of the boxing. My impressions are all from interviews. I obviously have no idea what he is really like, but see nothing to suggest that he is all that rotten.
