Zab Judah fought a good fight vs Cotto...and considering the only other guy to KO Zab is Kostya Tszyu that should tell you how hard Cotto punches.

Shane Mosley has NEVER been stopped and only once been down to my knowledge and that was vs a healthy Vernon Forrest who was a very good puncher until he got hurt. And if you watch the fight you can see Shane didn't enjoy being hit like that.

Margarito's chin is amazing...everyone who wants to KO him is fighting at a HUGE disadvantage.
