I played center in high school in the days when they could still smack down on the back of the center's head. Over the last 2 years of ball, I frequently would loose the use of my left arm for 5-6 minutes. Constant tremor in left arm for years later. At age 40, completely ruptured cervical disc. After fusion, No More TREMORS! As a physical therapist, I think Patrick and his family made the right but difficult choice.
