Im with AMAT on this one, Cotto is as cool and measured operator as there is in Boxing, sure he might get stunned but he keeps his wits and manages to be effective and dangerous even if he's seeing stars..

JMM wobbled Pac a few times with his counterpunching and IMO Cotto will inflict more damage at 145+ than Marquez will when he lands clean on Manny.
I am not convinced that Pac can take the kinda punishment a solid guy like Cotto can dish out.
