How SMOOTHNESS of a  SOCCER BALL affects curve!

Would you consider doing a mechanics analysis on heading a soccer ball and the implications regarding chronic traumatic encephalopathy; like what might the brain look like from the moment the body launches to moment of impact?
What about rotation of the head right before impact?
What about pure forward momentum with no body rotation. 
Will jumping decrease forces concentrating in the head and neck by transferring linear momentum in the ball to angular momentum in the middle axis of the entire body?
