If Sam elects to stay, this should be interesting. I don't think Sam has been seriously pushed by any QB since he's been in Horns. Despite the criticism of some, Sam throws a very accurate deep ball. He has been coached to be conservative thus far. However, with the receiving weapons now available, I could easily see him being encouraged to take more downfield shots.
As I noted before, AD could stand to improve his overall body strength, especially with respect to his arms and shoulders. I would hope his pocket awareness will improve over the rest of the season as he gets battle-tested by getting into more game scenarios. I can see him improving his footwork and delivery mechanics as well.
