I don't think anything tops Roy Jones' knockout of Virgil Hill. I remember Roy doing the Ali shuffle one time and then hitting his opponent with a right uppercut to the body so hard he reacted like he'd just been low blowed(when it was right to the center of his gut)

I think Malignaggi has the tools to beat Cotto. Cotto has the tools to beat Malignaggi but does he have the style.
