No, it was not Urban's or Mullen's duty to fix his throwing motion or prepare him for the NFL. Look what has happened since all these so called QB experts have started messing around with his footwork and motion. Now he cannot hit the broad side of a barn and thinks too much. If I fault Urban and Mullen for something is that they taught him to not turn the ball over too much and to only throw the ball when the receiver is wide open. In the NFL, you have to throw the ball in tight spots and you have to take chances. In college, Tebow could always scramble his way out of the pocket, not so much in the NFL. He also was rarely asked to throw slants and crossing routes which are the bread and butter of beat the blitz throws.
