It has been commented on before, but I think it is true. One of his weaknesses, and I don't mean to make it sound worse than it is, is that he is not particularly good at stepping up and throwing the ball. He prefers to run and buy more time. That is what an athletic kid lacking experience will always do. He got better at that as the year went on, but he preferred to scramble. THe problem in the Alabama game was that they blitzed five on almost every play, which cut off the escape lane.
Some of the scrambling may also be because he held the ball too long, also inexperience, not because of poor line play.
