If Margarito wins agaisnt Cotto this is the first time Mayweather will have had a reason to fight him. If Cotto wins this, and then fights ODLH or Pacquaio or whoever then he will have the name to draw mayweather out, but as things stand neither of them are that big of a name. I think Mayweather risked way more to himself in terms of losing when he fought Oscar at 154, who possesses speed, power, boxing ability, great chin, great level of competition.
