Not so sure about this one: Did Shane knock down Cotto on the way to his UD loss? I think I remember him not being able to.

Pacquiao, on the other hand, knocked Cotto down the first time with ONE punch.

According to what I saw in the fourth, it was a left that knocked down Cotto again - ONE left, which completely altered the demeanor of Cotto for the rest of the fight.

I'm not saying Manny hits the hardest in the division, but he done what Mosley was incapable of doing - of course, if I remember correctly.
