it doesnt matter who Floyd fights next, when he dominates like he always does, people will come up with excuses. Floyd cant win because nobody is at where he is at.
if he wins Cotto, he should have took Margarito
if he wins Margarito, he should have took Mosley
if he wins Mosley, we will get the "maybe Mosley was past it/a shot fighter/too old" argument
if he wins Pacman it will be the weight argument

If you ask me he should fight Pacman for the big money and then look into moving up a weight
