The first two are obviously the most compelling.

I really think that at this point, Diaz would break down Casamayor. Just such intense pressure Juan brings and he has a very much rounded skillset. And Casamayor is a bit past it. I think Casamayor would have his spots and it would be a good fight but Diaz is to much to cope with at this point.

I really think that even while Pacquiao is a huge step up in competition that this is a toussup fight. It would be the first time that Pacquiao wouldn't be the pressure fighter in a bout. Honestly, that would be perfect and break Pac from that merry go round of fights there.

It would be a great fight and Pacquiao would have to fight smart to keep from Juan Diaz from just mauling him. Pacquiao does have the power that Diaz would have to respect. Those would be great exchanges. That would be a great fight. And honestly, I would rather see that then a fight with JMM that just goes back over old ground.

Casamayor is to old for Manny here. I think Manny would basically have his way with him just because Manny punches come from everywhere and they are longer then Casa's.

Poor little David Diaz would just get slaughtered by any of them.
