Did Zab Judah even hit Khan on the Chin

I remember I thought Zab was gonna upset Khan, because I feel that Zab has decent power - Just ask Corey Spinks. I totally forgot if Zab landed anything significant on Khan. I personally think if Zab went in there wild like he did with Kostya Tzsyu, he could have got lucky and cracked Khans chin, I guess Pernell told him to box patiently, and that didnt work. In a rematch, I think Zab will go for broke, and will end up knocking out the punch drunk Amir Khan, Y'all thoughts.
