Cotto had a deal to fight Margarito if he won his fight against Williams. Apparently Cotto's team plans were to go for Mosley if Margarito lost (as he did). Cintron also wants to fight Mosley, and they were supposed to fight some time ago. But, we also have Williams in the equation. From these names we have some combinations and all are great.

Cotto (win) vs. Mosley; Cintron (win) vs. Williams = Cotto vs. Cintron (a collision of Puerto Rican Power)
Cotto (win) vs. Mosley; Cintron vs. Williams (win) = Cotto vs. Williams
Cotto vs. Mosley (win); Cintron (win) vs. Williams = Mosley vs. Cintron
Cotto vs. Mosley (win); Cintron vs. Williams (win) = Mosley vs. Williams
Cotto (win) vs. Williams; Cintron (win) vs. Mosley = Puerto Rican collision
Cotto (win) vs. Williams; Cintron vs. Mosley (win) = Cotto vs Mosley
Cotto vs. Williams (win); Cintron (win) vs. Mosley = Williams vs. Cintron
Cotto vs. Williams (win); Cintron vs. Mosley = Williams vs. Mosley (win)

If I have to see Cotto vs Cintron, I prefer to see them in a unification after beating all others (this has to do with my nickname)

147 is one of the hottest divisions, if not the hottest today, and there is for us to enjoy. And, here I'm just looking at the top not at the raising stars...

I am not including Mayweather in the equation at this point since I think that he may want to wait until the very end to participate on the action $$$ while these guys test themselves.
