Floyd Mayweather Jr. and Miguel Cotto will fight on Saturday, May 5, for Cotto's WBA Super Light Middleweight title and the vacant WBC Diamond Light Middleweight title.
But much more is at stake than these obscure belts.
Legacy, reputation and future mega paydays are on the line. A loss for Mayweather would be his first, and it would all but kill the chances of a super-fight with Manny Pacquiao.
If Cotto loses, he will have failed to score the signature win of his very good—if not great career.
So who's going to prevail? Here is my round-by-round prediction
