"How exactly? Since moving up he's been ktfo by Margarito, was backpeddling furiously in the later rounds against Shane Mosely and was in all kinds of trouble against Joshua Clottey"

LOL, these are the best guys he's ever fought. That could be why he had some trouble with them.

Bilbo's actually fought the good fight in some ways as concerned the Manny debate but this is reaching now. I think the debate about him fighting at 145 is a bit over dramatic though. Cotto's really a tweener. Too big for 140, not a very big welter.
