I personally believe that the De La Hoya “fatigue” factor has been somewhat overblown. No doubt about it, at times he has faded in the second half of fights. But which fights? The first time I remember Oscar having a noteworthy decrease in his skills during the second half of a fight is his first time against Mosley. I don’t think that it’s a fair description in the Trinidad fight since I believe that had more to do with over-confidence and a choice to stay away than it did with fatigue.

Since then, he was clearly beginning to fade against Hopkins, Mosley again. Overall, the stronger fighters he has faced who were able to wear him down physically. Remember, however, even with this “problem” of his, he still has shown an ability to carry his power late into fights. He knocked down Castillejo late in that fight (12th round I believe), knocked out Vargas in the 11th. Also, going back a ways, he knocked out Carr in the 11th and it was a strong finish against Quartey in the 12th that ultimately won him that decision.

De La Hoya may tire, but his power will still be there, and that’s what the biggest problem is for Floyd. Futhermore, Mayweather doesn’t have the physical strength that the others had to wear Oscar down.

I just don’t think it’s realistic to pin all hopes on Mayweather’s stamina and his ability to outlast De La Hoya.
