The initial post just makes it evident that you are praying for Mayweather to lose. If you wan't to break it down and make your case for Manny winning that's one thing; but to attempt to draw a comparison between this scenario and Roy Jones fighting Tarver and losing his form entirely since then, it's completely ridiculous. For one thing Roy Jones didn't even have to fight Taver whatsoever, and was clearly adversly impacted by dropping down in weight to do so. Mayweather Pacquiao is in a completely different league as far as public demand. Mayweather is also clearly thought to be more comfortable at 147, where the fight will take place.
