...ever make it back to the UFC? After Kerr's loss to Igor Vovchanchyn and the punch he took to his head you will notice Kerr's performance goes down hill. Of course all the drugs played a major role in that but so did that punch to the head. You can tell it's the first time Kerr had ever really been hit because if you will notice in every fight afterwards he acts afraid to fight/get hit/and punch. I guess the roids and speed turned him into the smashing machine.
