Not bashing anyone, just telling how I feel regarding the fight breaking down or postponing(I hope). We're fans of boxing before we're fans of Mayweather, Pacquiao or whoever.
Neither have a mental edge, although Manny maybe angry which could put him off his game. MAyweather has the massive skill advantage and thats the difference
Even the most adamant Manny fan has to realize that he is in for a rude awakening.. Once all the trash talk, drug tests, and fight hype in every thing will be settled in the ring. Mayweather holds every advantage besides one punch power, Mayweather is the better technical fighter the best defensive fighter in the game, adjusts better than anyone and has the same speed and better accuracy than Manny. Manny will be the agressor at first but once the fight wears one, Mayweather will assume control of the fight come mid rounds as he always does. Manny may even drop him but he wont stop Mayweather who is too good tactically to make enough mistakes for Manny to win.
If I were Floyd, I would take the fight with contract saying there would be a rematch. Win or lose you make $40 mil. In the second fight win or lose, with all the hype, Floyd can take home maybe +$40 mil!!! I would do it. With out the tests. If he is sure Manny is into something that wont appear on "regular" test why not take it himself to even the odds?
