Barring moving back up to middleweight, to fight Pavlik (ridiculous), challenging a young prime Cotto is about as DANGEROUS a fight as Oscar could take.

It would be a tremendous show of his LOVE for boxing (he certainly doesn't need to fight) to undertake that type of challenge.

Forget the MONEY angle, every fight Oscar has MEGA-money is attached, naturally the bigger the star in the opposite corner the more money involved.
