I would love to see this fight.
I think Cotto's tallest opponent was Sammy Sparkman..
I know that Sammy is no Williams but at least Cotto has beat up on some one much taller than him with a very large reach advantage too.

I want to see Cotto fight Williams, Margarito, Clottey and Cintron in what ever order they might come.

Also, I would love to see andre berto step up to cotto just for the fun of it. Arum was talking about having Cotto fight Alfonso Gomez. lol

I would also love to see Malignaggi move up like he said he would to face Cotto again. That would be fun to watch because of all the shiet Paulie talked he would only get sparked again but in a worse fashion.
