Why would Floyd have any trouble whatsoever making 144? He comes into the ring around 148 like Pacquiao, he wouldn't have a hard time at all making 144, I think Mosley and Cotto would have more difficulty, especially Cotto who is supposedly around 165 coming into the ring.

I don't think Pacquiao will make them fight at a catch weight, the more his opponent weighs the better for him IMO, It will just slow them down.
