Now that Manny Pacquiao proved he was right. What's next? Facing Floyd, that is. A thrilling idea that just became a concept: a what if. But why it will never happen? Because Mayweather Jr. want's to retire as undefeated. This is the only reason I can think of. If you say he fears Manny, I don't think so. I bet he can stand toe to toe with Pacman. He has the skills. He is undefeated. And he knows how to box. Now the question is why he wants to retire undefeated? Two reasons I can think of - money and/or prestige. You wont get anything else out of being undefeated except for those two. If you're undefeated, you're value goes up. You become famous. You have control over your fights... Things like those. Can't blame the man for thinking about his future. Specially if you have a colleague like Mike Tyson. Being reminded of how it will be without money will definitely make you think twice. I'm just not sure why would he choose a good retirement over...
