The Cotto fight is the only one I want to see, it'll get the casual boxing fan asking for the real fight of PBF Cotto if Cotto wins.
It would also show how much Oscar really has left, but it'd have to be 147 to make any sense at all. IMO it's decent logical fight for Cotto as I don't see him fighting Paul Williams anytime soon, though I'd love to See him fight Margarito, it wouldn't be as much of a statement as Oscar.

I'd actually give De La Hoya a decent shot against him, and with Cotto coming forward it'll make for a decent fight. The other two options I definitely do not want to see
