Paul has been a defensive coach through out his career. Some head coaches take on either the offensive or defensive coordinators responsibilities. The coach at TCU runs the defense and several other head coaches call the offensive plays for their teams. Paul cannot be happy with the way the defense has played the last couple of years. The addition of Mangino last year provides some hope for the future for the offense. Something needs to change for the defense. I think Paul should step up and assume responsibility for the defense.
