Reflecting on this a bit more, I actually think being unbeaten has an almost mystical quality to it.

Everybody loses, and hence is human, but someone who hasn't is still to an extent limitless and mythical.

Floyd has never been beat, and even though in our heads we all know everyone is beatable even his greatest critics on here subconsciously buy into his immortality as nobody ever picks any guy he's fighting to beat him.

Even Manny most favour to fall short against the mighty Floyd. Were he to have a loss that opinion would instantly change. Mosley is a joke opponent not worthy of even fighting Manny for example.

In sport people do still idolize and have hero's. Floyd's perfect record gives him a reputation that no other current fighter in the sport has. He would lose that reputation as soon as he lost a fight, and never regain it, as we would have seen his limits.
