No. 4: Commentators Will Try to Persuade Floyd That Manny is Vulnerable
It happens almost every time Pacquiao fights.
The words "he has landed more punches against Pacquiao than his last couple of opponents combined" are simply used to persuade Mayweather into thinking that now is the right time to make the fight.
At the first sign of Marquez's success, expect to hear that Pacquiao looks more vulnerable than he has before or in recent memory, and it will be repeated throughout the fight until the eventual end, however it may come.
Mayweather is confident enough in his abilities that he doesn't need to see when Pacquiao is or isn't vulnerable.
But, if it works, it could lead to the making of the biggest fight in a long, long time.
